Nano motor carrier issue

Hello,

I bought an arduino engineering kit. I connected a DC motor to the nano carrier, the battery to the nano carrier, connected the nano to the computer just as they said. Then I executed the following commands:

a = arduino; carrier = motorCarrier(a); dcm = dcmotor(carrier, 'M1'); start(dcm); dcm.Speed = 0.5.

The commands just executed wtihout throwing any error, but the motor didn't rotate. I decided to check the motor so I connected it to the 3.7V battery and it worked well. Any help would be appreciated.

Hello Stefan,

It sounds like you've set up your Arduino and motor correctly, but there might be a few things to check or adjust to get your motor running. Here are some troubleshooting steps you can follow:

1. Power Supply: Ensure that the battery connected to the Nano Carrier is fully charged and capable of supplying enough current for the motor. Sometimes, a low battery might not provide sufficient power to drive the motor.
2. Connections: Double-check all the connections between the motor, Nano Carrier, and Arduino Nano. Make sure the motor is properly connected to the correct pins on the carrier (M1 in your case).
3. Motor Carrier Initialization: Verify that the motor carrier is correctly initialized. Sometimes reinitializing the carrier and motor objects can help:

a = arduino;
carrier = motorCarrier(a);
dcm = dcmotor(carrier, 'M1');

4. Speed Setting: Ensure that you're setting the speed after starting the motor. You can also try setting the speed before starting the motor:

dcm.Speed = 0.5;
start(dcm);

5.Motor Driver: Check if the motor driver on the Nano Carrier is functioning properly. You might want to try controlling another motor or using a different motor port (e.g., M2) to see if the issue persists.

Hope it helps.
