I have the mini-rover tracked robot. Just finished assembling it and when I turn the power button on on the board the 6 LEDs will light up showing power to the board but the motors will not turn on. I used a voltmeter to check the voltage coming from the motor input terminals and it says almost none. I hooked up a motor to the 5V input on the board and a ground and it ran, so the motor is fine.
Does anyone know if there is something I am doing wrong or if I just got really unlucky with a bad PCB? Please help.
Sorry for the delayed response. Can you provide a few images of your setup?
The white JST connector on the DFRobotShop Rover Mobile Shield is meant to be used with a 3.7V LiPo battery, charged using the USB connector next to it.
You’ll need to ensure the 3.7V LiPo battery is charged.
If you’re able to make a 5V motor work using the battery, shield and code - it’s more of a question of the connection to the Tamiya motors.
Be sure to check that the wires between the shield and the motor terminals actually make contact. Remove the motor from he gearbox to ensure it’s not an issue with the gears.
Last, there is no sample code, so controlling the motors requires that the correct code be uploaded to the Arduino.
If you still have issues, please tell us step by step exactly what you are doing.
