After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.

This component includes the blink example. It can be used as a starting point when developing an application on Nano ESP32 board. Aside from the obligatory blinking of LEDs, the example also contains ...
