Automation, sensing and robotics • Re: Wiring multiple photoelectric sensors to RPI 4

Code:

    gpioSetMode(sensorPinWRoll, 1);    gpioSetMode(sensorPinRoll, 0);...        sensorRead = gpioRead(sensorPinWRoll);        //sensorReadb = gpioRead(sensorPinRoll);

I have only scanned the code, but are sensorPinWRoll & sensorPinRoll related to two sensors?
Do you intend to read the state from a pin defined as output? It looks odd.
