Hi,
I bought a PiRelay-V2, However it is not working.
I can run the test case, I saw the led on the board for each is flashing. However the relay is not triggered.
Raspberry Pi Gpio can only provide 3.3 volts
If I connect 5 volts from Raspberry Pi to GPIO, relay is triggered and led is even brighter.
So do I need extra hardware to make it working?
Thanks.
