Problem with FB Relays not working
I just received the relays in the mail today, and tried to test them out. When I connect them to the FB, and run the FB software, I turn the relays on with the skin, and the LED's on the board light for each one plugged into 0 and 1 on the FB.
I noticed there was no click sound when turning the relays on and off, even when holding one of them up to my ear. The temperature, Photocell and potentiometer are all working and showing correct readings on the analog in's, so communication with the FB is working perfectly.
I first thought maybe the wires were soldered to the incorrect place so I grabbed the multimeter, and it is showing .0023 volts on the header pins on the relays for both Digital 0 and Digital 1. Trying to narrow down further, thinking the plugs could be bad, I tested and get the same voltage readings directly fro the pins on the FB itself. The yellow lights are on for both the digital outs I am testing.
Isn't there supposed to be 5v on the pins when the digital out is on?
So, thinking that it was possibly a bad board, I grabbed the other FB I have here. I get the same exact thing with that one. The analog in's work, but nothing on the digital outs.
What am I doing wrong here, or is this a rare chance where both boards are not working correctly somehow? They are the 2 boards you guys sent me to replace the ones that were destroyed in my car accident. Thank you again! you guys are great!
