I’ve bought the 12V Brushless DC Encoder Motor for a design project. Before wiring up the motor to my circuit, I’ve decided to try and test the operation of the motor. To do so, I’ve followed the steps given in the documentation and resources supplied by dfrobot and uploaded the code to the Arduino. The first time testing the operation, it worked for about for a duration of time. I decided to disconnect every and try to connect everything back up to double check its operation. Second time round nothing happened. Repeated the steps made sure everything is connected properly and still no operation of the motor. Any suggestions what the problem may be?
