I'm using a Sainsmart UNO R3, and was wondering if there was a way to attach code to circuit without wasting the board.
For example, if I make a small lamp that when I tilt it, the light turns on. Simple stuff like that. I don't want to use a whole board in the circuit as it I will have to buy a new one. Is there a way to store the code onto another cheaper component and install that as part of the circuit?
(Not sure if that example would need an Arduino, but assuming it did)
