I just got started using the Raspberry Pi Pico kit and am going through the tutorials, specifically the tutorial on the centrifugal pump. As stated in the note section ([3.6 Pumping — SunFounder Euler Kit for Raspberry Pi Pico 1.0 documentation](https://docs.sunfounder.com/projects/euler-kit/en/latest/pyproject/py_pump.html)), if the pump is still running after clicking the Stop button, I need to rest the Pico by connecting RUN to ground. Is there a better way to stop the pump from running? I feel that if I have to constantly reset the Pico, it would eventually damage it. (Note: This is also an issue in [3.5 Small Fan — SunFounder Euler Kit for Raspberry Pi Pico 1.0 documentation](https://docs.sunfounder.com/projects/euler-kit/en/latest/pyproject/py_motor.html) tutorial) Also, I connected the relay, provided in the kit, to control the pump but, I am still getting that issue with the pump still running even after the Stop button is pressed. Any assistance on this issue would be greatly appreciated. Thanks in advance! ---

This is currently the only available method **If the motor keeps running after pressing “Stop”:** 1. Use a wire to briefly connect the **RUN** pin to **GND** (reset) 2. Remove the wire to restart the codde ---

Ok, understood. Thank you!
