Hi everyone, I had looked at expansion board documents for DRI0009 and DRI0039 at the time of applying for this challenge. It looks like they both share digital pins 4, 5, 6 from Arduino. Any suggestions for overcoming the issue? I was thinking of using a separate microcontroller programmed using Uno and use those both expansion boards separately that way. Any other ways to use them together?
Like shown in this tutorial...
Hi,
The '009 board is using the J1 pins 5-8 as just general inputs from the Arduino (i.e. Arduino pins acting as outputs), so you can move them to any other pins on the Arduino that can be used as outputs.
You can disconnect some jumpers on JP1 to isolate J1 from the rest of the '009 board:
..and then you could just patch the board by soldering some wires. It's up to you which pins you patch to. It looks pretty easy since there are spare through-hole pins along the edges of the board from where you can patch from, to JP1.
