I think I need to ask all of you arduino gurus etc for a bit of guidance, I have just received a 12v dc winch, and need to have it RC controlled by tommorow. I have (in the past) successfully controled things from one RC channel, so I am going to look for a copy of the sketch i used for that , i think i can make the sketch work,
My plan is to simply connect to relays to the winch motor terminals, so that it goes back and forth when they are turned on, then have the sketch control the relays accodring to the RC signal ,
Does anyone have any helpful advice on the matter? I am literally not going to be able to sleep until I have it done, and im tired :(
I am going to look and see how much the coil of the relay needs to power (AMPS) and then make sure its within the arduino pin limit, if not then i will hunt a transistor to do the job , hopefully a tip120 will get the job done, does anyone know the pin limit in mA?
thanks to any of you gurus that can lend a hand
