With this sketch you can control pins of a remote Arduino board through ESPHome. The Arduino acts as a port expander, allowing you to use more pins than a standard ESP8266/ESP32 has. The Arduino is ...

#define GroveDigitalExtender_SENSEHIGH_ADDR (0x06) // Interrupt direction 7-4 #define GroveDigitalExtender_SENSELOW_ADDR (0x07) // Interrupt direction 3-0 #define ...

Normally, I use it for IoT projects through the Arduino IDE, but this time I tried something different, flashing a NAT Router firmware to make my ESP32 act as a WiFi extender. Instead of relying on ...
