In the last picture of "How LEDs are made" it looks as if Alicia has a soldering iron arm.
Fortunately, I've got four of them allready ;-) Inspired by Secret Agent Laser Obstacle Chess (http://www.youtube.com/watch?v=AFol-Aiz8MQ), I once set up a laser diode, an Arduino and an LDR in the corridor at home. We had some guests at night and everybody got pranked.
If only Harvey Dent had watched the new products video about the new addressable RGU(ltra violet) LED strips...
According to this http://www.flickr.com/photos/johngineer/7329403498/in/photostream/lightbox/ there is a problem with using pin 2. I assume because it's physically connected to the SDA pin. I tried changing the bildr example code to use pin 4 and it worked! see also: http://forum.bildr.org/viewtopic.php?f=29&p=5808
Is there an easy way to get the actual input voltage of the lipo?
I want to measure the voltage and light an LED if it drops too low to inform that it needs to be charged.
I considered cutting the cables of the battery, but if there's another way it would be nice.
I'm confused by the data sheet. It says JP2 numbered from 1 through 6.
However, on the LCD JP2 is numbered through 10. What are the remaining 4 pins for? (and where can I find the documentation for them?)
Thanks! It's 5 V.
Another thing I could not find out here is how to connect an Arduino bootloaded MCU to the DTR.
After a little bit of google search I found out that you need to put a 100 nF capacitor between DTR and the reset pin (pin 1 in case of a atmega328). In my case, just connecting reset and DTR did not work.
Maybe you could put this information into the description.
I just got one via a local store. On the top it says 3.3 V but on the bottom the trace is set to 5 V.
What is it? 5 V or 3.3?
Hi, guys!
Is there any estimation when these LCDs will be back in stock again?
