| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | Motors don't spin | No power to Vs terminal | Connect 6V–12V battery. | | Motors spin but Arduino resets | Insufficient power or missing ground | Connect GND of battery to shield GND. Use separate battery for motors. | | Motors only go one speed | ENA/ENB jumpers still on | Remove JP2/JP3 to use PWM. | | Overheating quickly | Motor stall current >2A or voltage >12V | Reduce load, add heatsink, or lower voltage. | | Current sense reads zero | No jumper on CS pin (or motor not running) | The CS pins are open by default; you don't need a jumper—just read voltage. | | Shield gets very hot | PWM frequency too low (audible range) | Default 490Hz on pins 3/11 is fine. Don't reduce frequency. | | | Motors only go one speed |

| Function | Arduino Pin | Description | | :--- | :---: | :--- | | | D10 | PWM control for Motor 1 (0-255 speed) | | M1 (Dir M1) | D12 | Direction control for Motor 1 (HIGH/LOW) | | E2 (Speed M2) | D11 | PWM control for Motor 2 (0-255 speed) | | M2 (Dir M2) | D13 | Direction control for Motor 2 (HIGH/LOW) |
