One of the parts in my circuit is heating up, what should I do?


#1

First of all, disconnect the circuit from the power supply.
Then, there are a few things you need to verify:

  • Make sure that you used the correct components (for example, there are some capacitors that look like a one-wire temperature sensor).
  • Check that the polarity is correct
  • Go over all the steps again and make sure that you connected everything properly and according to the wiring guide.
