Re: How to conect solenoids to the circuit board. and how to program it...???

Solenoids draw quite a bit of current, so you can't connect them directly to the RC, they need to go through a relay. How you wire it depends on the valve you are using. Generally speaking, the relay will put voltage on the solenoid coil, which will in turn cause current to flow, creating the magnetic field that opens the valve.

So, you need to wire the solenoid to a relay output, then wire the RC to the relay using a 3-pin cable connected to the RC relay header.
