Stupid Mistakes Playing With Electricity

3D Printing switches in Arduino

I am arriving at the end of this project! Here are the list of materials I have used to make this possible.

Parts List:

  • 1x Breadboard
  • 1x Arduino Nano
  • 1x 10K Ohm potentiometer
  • 1x switch
  • 4x M5 screws
  • 1x ESC 30A
  • 1x A2212 1000kV Brushless Motor
  • 1x LiPo Battery (2S or 3S)


  • 3D Printer
  • Soldering Iron
  • Drill


.STL files:

After printing out the design, you might need to enlarge the holes to mount the brushless motor depending on how precise your 3D printer is.
