So guys I'm working on a little project which involves controlling two AA batteries. I'll have the batteries in series to get the power I need so there's only two cables to both batteries.
I'll need to be able to control the batteries with some sort of switch with the 433 MHz transmitter and reciever. How could I do this? I have no clue what to do with the wiring or the code.
I'd like a small electric engine to be controlled in the end (on an rc car). So that's why I need the two AA batteries. I could use the arduino 3.3V but the Amps are way to low to crank the engine.
