Multiple Peggy2s displaying serial video

Arduino Technology

Ian from weezey.com wired up a couple of Peggy2 light emitting pegboard kits to an Arduino and with a couple of tweaks to some existing code managed to get the display to run across both units. [via hackaday]

The code changes were actually quite simple, I made a second header and data array so that the second Peggy2 has a different header that it acts on to change it’s state and then coded that into the sketch for the second Peggy2. I looked at changing the TWI address first but I think the Arduino code would need to be modified for that and right now it just spews data without modification and I didn’t want to mess with that yet.
