  1. Hi Aisling,

    I think the problem with the state changes are to do with missing curly brackets in the if statement where you check _RD3 (the switch input). I think you need something like this:

    if(state == OFF) // Motor Off
    LATD = 0b00; // off
    if (_RD3 == 1)
    while(_RD3 == 1);
    state = LOW;
    printf(“OFF\n”); //monitoring

    Without those middle set of curly brackets, “__delay32(pause);” and “state = LOW;” are not conditional on the if statement – they’re just executed every time.
