Arduino Buzzing When Trying to Output to Motor

Help & Support Robots & Kits

Hi!

I require your help regarding a problem I’m encountering.

I screw and output voltage through 22 gauge wire as an input to a motor, and when I complete the circuit to the motor, the Motor 1 (M1) LED above the positive lights up red, and is accompanied by a terrifying buzzing sound from the board. What happened? What should I do? The other side is working just swell. This side used to output very little voltage, and now this.

This concerns the DFRobotShop Rover V2 - Arduino Compatible Tracked Robot (Basic Kit).

I am outputting the correct motor voltage, as the same voltage used to work on both motors a long time ago.

Measured the voltage with a multimeter, and it is about 1 volt max on the side that isn’t working. The side that is is about 5 volts.

It is the circled LED and the motor output right next to it.

Thank you so much in advance for your help, and please contact me if you would like more information!

A “terrifying buzzing sound” is certainly not normal. Can you check that the wires are not touching somewhere or the motor cannot rotate properly? We’ll have more details soon.

Can you probe (with a continuity test of the multimeter) the two motors inputs of the screw terminal of the non working side and see if there is a short ?

Thank you for the assistance everyone! I can ensure that the motor wires are not touching and the gearbox is functioning properly. I do not have access to a multimeter at the moment, but I will check the continuity. Thanks!
