Video grove pi+ working
I’m turn on D2 and next D3 But relay turn off all.
When use turn on volt meter D2 have 3.0v
and turn off 4.7v
Usually I used Grove pi+ power supply 5v 3a but relay does not work at all so what kind of power supply that I should use?
Or is it another problem?
Can you show us the code you’re running? And second of all, can you try explaining more clearly the issue you’re experiencing?
Are you saying the relay on port D2 should be the only one to turn off instead of having the D3 shut down too?
