When i had the relay hooked to PI 5v pins, the relays snapped on, and locked on. A friend who knows electrical mentioned 5V may be influencing a resistor or something else in the relay had locking it on. The 3.3V from the pi fixed it.

SUCCESS!!!!! I turned OFF the enable button on the left and they work! Relays are snapping. I found other threads that mentioned this as a possibility. I've been on and off of this for the last year! Probably no fancy show this year, but I'll work on it for next year. Then ---pixels...

The card is a Sainsmart 16 channel relay SKU: 101-70-103. The pins on the relay have 5V printed on them. I have tried both the 3.3V and 5V outputs from the Pi. The 3.3V on the Pi to the 5V pin on the relay got them to work when I have the Regular Pi SD card in and run simple scripts to snap...

Can you please post a screen shot of the FPP Output? I have a similar setup but can't get the &@$#*@! lights to blink through FPP.

Same situation for me. Last year, I built a waterproof box with a Pi 3 and a 16 channel relay board. Trying to simply blink stands of lights on and off to the music. With a standard SD card to write Python Scripts, I can turn 16 channels on and off individually and in groups. The Pi to Relay...
