I have been trying to interface the video experimenter shield with the arduino nano, and it doesn’t appear to be working. I’m pretty sure I connected all the appropriate pins on the nano to the corresponding pins on the shield, but when I feed the video signal in using the overlaydemo program, all I seem to be able to see is the output from the signal generator. I think the problem might be that I did not interface the correct pins on the nano to their corresponding pins on the shield, although any input on this matter would be greatly appreciated.
*It uses the AT328P.
*I connected D9, D8, D7, D6, D2, REF, and A2 to their corresponding pinds on the shield.
*I found out something a little while after I posted. It turns out there was no power being supplied to the chip from my setup. Also, the input and output video jacks did not have their grounds connected. When I fixed all of these issues, the board gave the proper output. Unfortunately I will have to solder in jumper wires to the correct places on the board if I want this setup to function normally.
You should be able to supply 5V to the 5V pin on the shield, and connect the shield GND pin to GND on your nano and everything should work, no jumpers on the board needed. The ground connections on the RCA input and output are connected together. All board grounds are connected to the GND pin.
