Motors, are generally heavy duty, which means, connecting it directly to the controller pins may end up frying it up! So, to source higher +current, transistors or motor driver ICs are used. These are great as they can be easily used to turn your motor in either direction, just by giving digital high or low to the input pins of L293D Motor Driver IC. The easy part is, controlling the speed can be done by just changing the voltage bias given to the driver IC. + +Components required +------------------- + +OpenPLC board + +DC motor + +Switch ON motor +--------------- + +In this experiment using an input switch, PLC turns on the motor connected to it.
