in FIRST terms a relay is called a spike
ahh. i see. thanks. but then you dont have proportional control over the 12V motor right?? with a motor instead of a relay, you CAN get proportional control over forwards and backwards. a little complicated but yes, possible
maybe a servo will make things easy for that plan of proportional. a stepper motor will also work. just the wiring and programing might not be as fun or easy.


off-topic. i love these threads(questions on whatever). just a really nice way to learn more by reading everyones replies and then learning where your own knowledge is wrong and getting new ideas, expanding on those ideas. its really inspiring!!
