Description: Got too much data for 10 measly segments? This kit contains a PCB and all the parts needed to build a 30-LED bargraph that can be driven by an Arduino or other microcontroller.
This kit uses our 74HC595 shift registers and 10-Segment bargraph modules to create the display. We supply one green, one yellow, and one red module for ‘safe / caution / DANGER!’ displays. The display is easily driven by a microcontroller using an SSI interface, and you have individual control over every LED.
Note: This kit comes unassembled and requires basic soldering skills. The included resistors may vary in color depending on our supplier.
Note: The pinout on these bar graphs may vary from what is listed on the datasheet. Before soldering your kit into place, we recommend testing the polarity on the LED bar graph to confirm its orientation.

The board arrived pretty quick. Assembly is very simple. I used the picture to orient the parts, and guess what - the way the LED block is shown in the picture with YS facing the IC’s is incorrect. I learnt it the hard way and had to desolder the 3 LED blocks and remount them. Desoldering showed me that the quality of the PCB is pretty good. However if I were to do it again, I would assembly only one 74HC595 and one LED block. Then check it at that point. If all worked well, i would assemble the rest. The purpose of me getting the board was use 4 DIO ports on a Keithley 2400 power supply to control 128 relays. I used DIO#1 for CLR, DIO#2 for CLK, DIO#3 for LATCH and DIO#4 for SIN. This board gives me a visual if I will be setting the relays correctly. Now that the HW is all good, I can focus on the SW development & extend the concept to 128 individual controls.
This kit arrived in a timely manner, no delay, like that. Actually read the installation document before its arrival, and it’s a well written and well illustrated paper, I really learn a lot from it. If you follow the procedures, as I did, and don’t skip any step, you’ll be rewarded with first-time power-up success. It works for me 100% Overall, this kit is well built and the PCB is supra. Oh, I had a great time putting it together. You got one happy camper here.
Despite some initial confusion about manufacturer-mispackaged bargraph LED arrays (and having to replace one,) got this breadboarded and up and running with the example sketch. Fantastic results! Now to find a use for it grin 10/10 will buy more parts to build more circuits along these lines
