LEDwall Proto 3

Ahh, Christmas holidays. The perfect time to muck about with electronics and software. I never thought I’d enjoy electronics this much.

Admittedly, I didn’t make a lot of changes the LEDwall prototype, I just finished it up. I soldered the base of an Arduino Nano to a little soldering board, installed the Nano, trimmed some wires and I added proper connectors instead of twisting wires together and applying duct tape.

I got rid of the GUI and networking stuff that would allow me to set the program remotely. Instead, I added a little jumper to be able to switch the program every time the Arduino starts. Then, I wrote some code to turn the whole thing into a `Do not disturb’ / ‘I am available’ sign.

Besides the two shown above, I’ve also made a blinking display of the letters ‘O-K’ and ‘N-O’ in green and red respectively. It’s a bit painful to look at so the first option (green circle and red cross) seems most useful. If the jumper isn’t here (if I’ve lost it 😉 ) it shows a spiffy flashing raindrops thing that is sure to induce an epileptic seizure.

Happy holidays!
