Troubleshooting
Certain power supplies have a lot of noise. While 12V/5V power supply works great with a
microcontroller and a LED strip, it may not work as well when you attach a capacitive touch sensor
to the system. The power supply lacks proper filtering and causes the potentiometer to have a lot of
latency. You can try to add additional circuitry to fix it since the current power supply has a lot of
noise. However, it would be easier to use two separate power supplies or a more robust power
supply such as a Meanwell.

Now that you’ve successfully got your 12V/5V power supply up and running, it’s time to incorporate it
into your own project!
