Motor shield is not working when I use an IR receiver. I tried connecting the ir receiver in different analog pins but it didn't work. I guess it's due to some error in my code but unable to figure out.

  • Is the motor using pin 1?

  • Yes I've connected the motor to pin1 also. I tried running the motor using a separate code and its working fine. @Delta_G

    That seems unlikely but if true explains your problem. If it is using pin 0 or 1 then you can’t use Serial. What motor shield do you have exactly? Do you have a link?

    Are you sure it's the V1 and not the V2?
