Hi Everyone,
I am trying to improve my coding skill. Here is my scenario:
I have four ports which connected to four DC motor. The default state of the ports is set to '0'. I change the ports state to '1' for turning on all the motors. When I disconnect one of the Motors from their port, one motor will be off because I disconnect it. But the other three are still running. How do I know if my ports is connected to any device such as DC motors? Can anyone show a sample code?
Thanks!
Regards, Sharil
