outputs a value of 0. In addition, you can adjust its sensing distance through the potentiometer on the module.

Now build the circuit according to the diagram below.

Note: Before starting the project, you need to adjust the sensitivity of the module.

Wiring according to the above diagram, then power up the R3 board (either directly into the USB cable or the 9V

battery button cable), without uploading the code.
