Re: Raspberry Pi + relay GPIO dont work

Thanks everyone for your help. I had buy the new relay. I had try the relay with an arduino nano and it's 100% OK. So now, I had to choose between : 1 - Wait for delivery 2 - Buy a digital level converter 3 - Find a way to make rpi give order to arduino nano. 4 - Test PhatFil solution (pull down) Th...

Re: Raspberry Pi + relay GPIO dont work

@tlfong01 Any advise on : But meanwhile, I would like to explore the : 2. Shift up the Rpi 3V3 GPIO signals to 5V0, problem would disappear. I have some 3.3K and 10K resistances, I must connect a 10k resistance between GPIO PIN 40 and 5V ? If I understand, PhatFil, you suggest the opposit ? I suspec...

What is the specification of your motor? Because you might need a other relay for this task.
I don't know, this is a bath tub 500W balneotherapy Pump.
But the relay works fine when On or OFF, my issue is on trigger

Re: Raspberry Pi + relay GPIO dont work

Hi, Thanks for your quick answer. I love your risks, especially the LOL from Arduino users. About solution, 1. Throw away the Arduino only relay, buy a High trigger one instead. Done :) Is this one better ? (1 Channel) https://ae01.alicdn.com/kf/HTB1DZYVa6rguuRjy0Feq6xcbFXaL/Un-1-2-4-8-Canal-5-v-Rel...
