Arduino Milestag
An implementation of the milestag protocol and some game mechanics intended to run on the arduino. I possess no skills (or tbh, interest) in hardware and as such, an arduino with a few led's wedged into it seems like a good platform :-P Since starting the project, we have become more interested in using the arduino as a hardware interface and putting all of the logic onto a raspberry pi.
Electronics
I still have to enhance the electronics so that the IR LED can be driven at a high enough power to be useful. until then I am using the following electronic circuit:
Arduino 5v---------------\ | LED1 | | | R1 | IRR out---/-------------- 12 \--IRR Vcc /--IRR Gnd /----- 8 | R2 | | | IRLED | \----- 9 0v--/
- LED1 is for monitoring the reciever
- R1 is massive overkill just needed to protect LED1
- IRLED is set with the cathode (-ve) to pin 9
- R2 is an R270 giving about 20mA through the IR LED. It should be able to handle > 1A for real.
