I just started playing with Arduino and processing for a school project. I bought a relay shield from dfrobot. And i didnt want to shortcircuit my arduino so thats why i come here to ask this:
I want to switch the power of a Showtec Par 30 on and off with the arduino. I will figure the code out but i have no idea to connect what cable to what port.
I have these ports: Nc1 com1 no1 ground and 9v. Could someone explain to me what they are and what cable to connect to what slot?
And another thing: If i have the shield on can i still use the 5v gnd and a0 from the board cause i will still need those to control a servo.
Hope you guys can help me.
Thank you in advance!
