Hello.
I am using a "41468 motor shield" (images attached).
It seems to work ok for motors but I want to also put an IR sensor so that I can start/stop motors from remote controls.
Where do I connect the IR sensor? It only works on digital pins, right? Or analog is good too? Because the card only seems to have the analog pins available, I soldered connectors on the analog area (the 3 lines of 6 pins).
Is the digital area fully occupied or can I connect sensors there too? Some digital pins: 0,1,2,13 (marked with black marker on the side of the board on 3rd image) seem to be unused from what I see. Can I connect IR sensor there?
Thanks.
Can you also tell me if this shield can be used with one of those simple 2 wire motors? Or it only works with 3 wires?
And can a 2 wire motor be made to change direction with this shield ?
