Hello, currently I am having a problem when I connect the PI(zero 2 W) to 2 relays irf520 (gpio 13 and 37) |

Hmm, this is a dimmer. And my documentation says all GPIO ports can be used. But I get the feeling that it will work better by using the following physical pin numbers: 12 and 33. Those are PWM pins, which I think will better work with dimmer relays. https://pinout.xyz/pinout/pwm But that means that you have already have the max amount of dimmers you can use safely. There are two more PWM pins left, but they are combined, so despite the 4 pins, I can only use 2 for dimming.... |
