_images/img.png

You will need:

  • A table tennis ball

  • One white breadboard

  • Wires

  • One LED wth a LED holder

  • One wire holder

  • One ESP32 development board

  • One 110 Ohm resistor

How to proceed:

  1. Take the tennis ball, and make a hole in it, not too big, but sufficient to be able to mount the LED hold

  2. Connect a wire at each end of the LED

  3. Mount the LED holder into the hole of the tennis ball

  4. Now, assemble the wire holder, with, at both ends one of the wire of the LED. Pay attention that the longer “foot” of the LED will be connected to the ground

  5. Mount the wire holder on the breadboard

  6. Take the ESP32 and look at the pin. Locate the pin number 27

  7. Plug in the dev board on the board

  8. Put a wire from the ground to the ground line of the breadboard

  9. Plug in the resistor at a free space of the breadboard

  10. Put a wire from the pin 27 of the processor to the resistor

  11. Put a wire from the resistor to the one side of the wire holder

  12. Put a wire from the ground line to the other side of the wire holder

  13. Plug it in and test it with Thonny, see also Usage or continue reading
