Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

  • For those having problems try this. With the pins at the top pin 1 is next to the edge. I'm using an Arduino ATMega 328 mini pro.
    using the example Hello World arduino sketch.

    3 = resistor ~2-3K to gnd
    4 = rs = tie to pin 12 on arduino
    5 = r/w = tie to gnd
    6 = enable = tie to pin 11 on arduino

  • PicaxePete / about 14 years ago / 2

    Working OK with Picaxe 20x2 but uses pins I would like to have free for i2c. So, I am getting bigger picaxe to go with it. Used 2 rectifier diodes in series for the voltage drop to 4.2v on the backlight and two 1k ohm resisters in series for the contrast. Looks good.

  • Pyronox / about 14 years ago / 2

    Thanks loophole! I got the display working fine using this link that link that was mentioned,, but it was dim since the backlight was not working. After reading loophole's comment and looking at datafile I applied 4.2V pin 15 and grounded pin 16, and all was GREAT!
    Note: To get around 4.2V I just ran it through two IN4004 diodes.

  • Chris29 / about 15 years ago / 2

    Works fine with Arduino and LiquidCristal library.
    Needs a lcd.clear() in void setup()
    And don't just ground the contrast (V0), use a pot or you won't be able to read anything.

  • bosst / about 9 years ago / 1

    How bright is this? I would like to leave it on in the dark but not have it too bright such that it looks like a light source. I'm considering getting this vs. the standard black on green since it looks nicer but hoping its not too bright in the night.

  • Member #533062 / about 10 years ago / 1

    I already fried one while soldering on the headers, now I think I ruined a second one. I have it wired up the way KHartley describes, but I only get backlight, no text, even when simply uploading the Hello World example sketch. Assuming I didn't destroy it, does anyone know why this might be?

    • Play around with the trimpot setting. If you still aren't getting any results, make sure you don't have any solder jumpers between pins.

    The post that KHartley posted with regards to all the pin connections and using an Aduino mini pro, who then also got a reply from member 468163, that the code and everything worked.

    I am using the exact components and have followed the exact pin configurations for the past 2 weeks, connecting then reconnecting, I have also tried different FTDI cables for uploading onto the Arduino pro mini. BUT have had no success, PLEASE help me as it is a basic issue I am sure but cannot find the solution, My 16*2 LCD lights up and also when I upload a program the arduino page reads that it has successfully uploaded (Done Uploading).

    I have seen that the other alternative or different way of setting up the circuit is by using a resistor instead of the 10K potentiometer that I am using.

    Any suggestions?

    can this run in 8bit mode? I'm trying so hard to just wire up the 8 data lines and manually send the bits required for certain symbols. But it's either stuck in 4bit mode, or I'm completely lost. My program is simple and I KNOW that it is sending the 1's and 0's down the appropriate lines but I can't get a response at all. And I can succesfully apply the example code for liquid crystal. In class we just banged some bits into those old lcd's and got the expected response... Is this one more advanced or something? Thanks, I really appreciate any help.

    I'm having a problem with this lcd, I can'd print custom caracters, I tried the code that this site gives you when you create a custom char, tried some other examples, but nothing, I always get just two vertical bars on the second and fourth columns.
    Is it a compatibility issue with this controller (it's a SPLC780D, not a HD44780 as said in the description).
    BTW, it can display normal characters just fine.

  • Brandonious / about 13 years ago / 1

    I love this little LCD! It works great. However, I'm having a wicked hard time finding hardware (i.e. self-clinching PEM stud) that I can use to mount this. The 2.5mm mounting holes are pretty small. I'm trying hard not to use glues.
    Any suggestions, anyone?
    Thanks in advance. :)

  • WizenedEE / about 13 years ago / 1

    I'm having problems with my contrast - it's always either too high (washed out characters) or too low (can't see the character) on separate spaces at the same time. No matter how I adjust it, each character seems to require a different contrast level. Help, please?

    • GeneralERA / about 13 years ago / 1

      I'm also having problems with contrast; I'm using a 10k pot on the contrast pin, and it takes tiny adjustments to make it work. After a minute or so running, the contrast starts to flicker, and I can't seem to get it stable.

  • cptbjorn / about 13 years ago / 1

    Like others have said, works well with liquidcrystal library and I also like to pwm the backlight with a fet on the low side. Looks really cool to have it fade out to 1 or 2% duty cycle standby mode when there has been no button presses/input in a while and then fade back in when you press a button.
    Also no external resistor is needed for the backlight; just like almost all other 5v character LCDs this one has a series resistor right on the board. Mine is 130 ohms.

    Serial lcd(p13,NC); // NC = not used

  • Works Great! Used with the Arduino and LiquidCrystal. Very clear and easy to read. I originally was setting contrast with a PWM pin to see how it worked(AKA I forgot to buy a trimpot), but it made the screen 'pulse'. Switched to a potentiometer I scrounged and that worked much better. Ive got the backlight hooked to +5 and its been working fine so far.

  • joe-c / about 14 years ago / 1

    I was able to achieve much better contrast by applying a slightly negative voltage on the Vo pin (3). Minus 200 mV did the trick. I seem to remember that LCD's used to have a negative output for just this reason. I don't know what the rating of this pin is, so proceed with caution.

  • Technobly / about 14 years ago / 1

    For those of you trying to hook up the LED backlight, here are some things to consider:
    1) The spec sheet says 120mA typical, 160mA max. for the backlight.
    2) The backlight is a 4.2V forward biased LED, so pin A (or 15) is the anode and K (or 16) is the Cathode.
    3) If you hook it to an Arduino, powering the LED backlight from a digital I/O pin will only source 40mA max. (PIC micros are even less), any more and you are overloading your output. Tie pin K (or 16) to ground, and A (or 15) will be the high side. If you design for 40mA, calculate the current limiting resistor to put between the I/O pin and pin A (or 15) of the LED backlight as follows: 5V-4.2V=0.8V and 0.8V/0.040A=20ohms however, be sure to measure the voltage across your current limiting resistor and calculate the actual current flowing to the LED just in case... don't overload your Arduino I/O!
    (more continued below...)

    • Technobly / about 14 years ago / 1

      4) If you want to really drive it properly, you need more POWER! So grab an NPN transistor such as a 2N4401 or 2N2222 or 2N3904, and amplify your I/O. Hook a 220 to 330 ohm resistor between your I/O and the base of the NPN, hook the emitter of the NPN to ground, and the collector to the K pin (or 16) of the LED backlight. Hook a 5 to 10 ohm 1/4W resistor between the A pin (or 15) of the LED backlight and the 5V rail (make sure your 5V regulator can handle the extra 120-160mA of current you are going to be consuming)

      • tzikis / about 13 years ago / 1

        what is the reason for the 5-10ohm resistor between the anode and the 5v? Someone mentioned that there is already a 130ohm resistor on the board in series with the backlight LED, so i can't find a reason for it being there.

      • Technobly / about 14 years ago / 1

        Oh, almost forgot... if you make that I/O a PWM output... you can then vary the brightness from 0-100%

  • godzillatron / about 14 years ago / 1

    Thanks to the guy who did that wiring up diagram at Aruduino.
    Thanks to the guy who first pointed that for that bcklight to work one needs pin 15 on +4.2V and pin 16 on ground. Without that I was getting a pretty dim job.
    For me, 82ohm resistor produced exactly 4.2V, on the pin 15. 10ohm resistor was giving me around 4.8V. Since I've no clue, better safe than sorry.
    It is a brilliant little LCD. Really looks cool. I bought it for the looks ;-)

    • N.Poole / about 14 years ago / 1

      yeah, I've got a 110ohm on it. Still very bright, reading 3.8v or something in that ballpark.
      This things freakin' great.

  • brainbag / about 14 years ago / 1

    I made it work by using the same schematic featured in the LiquidCrystal Arduino library page, except LCD pin 6 is hooked to a digital PWM instead of a potentiometer for controlling contrast.
    I used a 10ohm resistor for pin 15 to drop the backlight voltage, it works great and looks just like the picture. Pin 16 is hooked to ground.
    Very nice, bright, easy to use LCD!

  • loophole / about 14 years ago / 1

    Pretty cool little LCD. I had some problems initially with the 4bit LCD library, but after finding that the standard LiquidCrystal library supports 4-bit data lines it worked great.
    The one thing that threw me off was that the standard (not extended) datasheet mentions that the backlight (BKL) can be driven by pins 1,2 or 15,16 -- however I found that I needed to apply 4.2v to pins 15,16 before the backlight would work. Easy fix, just misleading on the datasheet.

  • Anonymous / about 15 years ago / 1

    I'm very impressed. I followed the connections from the data sheet and set them up the same way the LiquidCrystal "Hello World" example sketch calls for, and the display worked perfectly with my Arduino Duemilanove. It does take some playing with the contrast potentiometer, but I quickly found the perfect setting. The display is sharp, clear, and cool white letters on a black background.

  • Ordered mine a week ago and finally got around to playing with it. I used the included LiquidCrystal.h for Arduino to run this thing. Very easy to use once you get it up and running. To get the contrast working I used a 3.3Kohm resistor going to ground, looks amazing. Not quite as bright as picture but I think I'm close. 2.2Kohm is too washed out and 6.8 Kohm nothing shows up. I can't believe how much easier this is compared to the 68HC12. Uhhh, I'm going to have nightmares for the rest of my life.

  • VadimK / about 15 years ago / 1

    Hey I'm thinking of buying one, but I'd like to know. How bright is it, I'm thinking of using it on a buggy to show fuel, tack, and speed. So it will be vibrating around in bright sunlight. My question is, will it be legible?

  • Characters on mine look very dimmed! I'm using a potentiometer, however when powered up doesn't look anything like the product image thumbnail.
    I'm following the schematics from Arduino website:
    It works fine with my second LCD (black on green) but not with this one (white on black).
    Am I missing something?

    • Denny / about 15 years ago / 2

      Have you wired in the backlight? That tutorial doesn't include wiring pins 15 and 16 on the lcd. I have hooked the backlight up to a pwm output so that I can turn it on and off via sketch.

    • Avenphire / about 15 years ago / 1

      I'm also having heaps of trouble. I can sometimes get it to display text, maybe once out of every 30 attempts. And IF it decides to display anything it ends up garbling the message and locking up, not displaying the other strings in the sequence. Is this the LCD, my Arduino or the library? I tried using LCD4bit and a modified LiquidCrystal and they all yield the same, frustrating results.

La primera que recibí se me estropeó

Tuve que cambiar la primera que compré porque empezó a oiscilar la iluminación de la pantalla.

Por lo demás todo muy bien, buena presentación y buen funcionamiento.


I love these screens.

The display is clear and the characters are legible. I do wish this display supported more than 32 characters. As for interfacing, that is very easy. Just a hand-full of switches (and one potentiometer) and an ASCII chart you don't even need a microcontroller (but you'll only be able to print one character every few seconds without one).


Display is Much brighter than the picture, and even though it was a bit scary to solder onto (im a bit of a newb at soldering) , it works fantastic! So bright, Very responsive. I dont even have the display at its brightest and it is a crystal clear read! Look forward to using it in my summer project.

Good Quality LCD

The LCD arrived promptly in the mail and worked as advertised. If my experience is typical of Sparkfun, they have good products and are very efficient.

Strait Forward

I wired up the display and ran it with the standard Arduino library. Worked first time!

Narrow viewing angle, Color Inversion

Apparent color changes from white-on-black to black-on-white at ~ + 5’ and ~ -20’. Readable until ~ + 35’ and ~ - 80’. During the color change, it’s difficult to read; a lot of head bobbing is required. Readability at greater + angles would be better for my application. Is there any way to flip the text orientation or, perhaps, another hack to improve upon this issue? I won’t be purchasing this product again.

Shipped defective,,didn't work


Sorry to hear about the issues with the LCD screen. Have you contacted our technical support department @ - they're usually great at helping sort out defective products for people and getting them working components.

The contrast is ideal for viewing, day or night

I used this display in a DDS VFO. The contrast of the display is great for viewing at any angle day or night

Basic 16x2 Character LCD - White on Black 5V.

This LCD works as advertised. The software compiles from the Arduino library only for version 1.0.5-r2. These LCD units are well made, but do not drop them on a hard surface as the electronic seal to sensitive glass surface will fail to make proper contact. Most of the test examples in the Arduino library work great. My unit shows black on white.

Looks great. Works great

I bought it to fit into a homebrew DDS-based VFO for my vintage ham station. Most of the various color displays just don't look right with all the dark somber enclosures of the period. This mostly monochrome LCD fits in fine if one can accept a DDS device in a tube environment.

But it's certainly bright and showy INSIDE with it's red PCB.

No Issues

Works fine with a Raspberry Pi 3 an the white on black look really nice.

works well

its does exactly as required. easy to use and mount

Couldn't be happier

Works as it's described, would recommend to anyone. And if any issues sparkfun support can help as they did for me. Overall satisfied
