About to complete Ardbir build with Daniel Xan pcb. I'm stuck with pump reley. I'm using arduino 1 chanell relay for pump. There are GND, VCC and SIG , in total 3 pins on relay and only 2 GND and SIGNAL? from Ardbir module?
Also is it normal that SSR is blinking while Artbir starts?
Is it OK to use PC CPU alu cooler for SSR?
