Welcome to CNC
Great idea! Not sure about the embedded RFID lol, but I love this! How about for strength purposes just using a solenoid of some sort?https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTeQ7a16k-D8Ur2a6KS6KASIb5xJqoFKUp8nyXFsioDtPR-Z1y4
Very nice! I am one of the owners of www.galaxydrumlights.com. We started out much the way you have done there although we started with an analog system. It wasn't until later that we moved into microchips. Great job!
I was looking over your tutorial here and I am confused about one thing. You show going to the TX (transmit) pin on the arduino. Aren't you sending info to the arduino from the attiny, in which case you should use the RX (receive) pin?
