This repository is a work-in-progress implementation of microcontroller software (esp. Arduino Nano, 5V) to interact with a Junkers Cerastar ZWR/ZSR series gas furnace. These gas furnaces are ...

Arduino Nano 168 Arduino Nano 328 (ESP8266/ESP32) The source code was tested for Arduino Nano 168 and Arduino Nano 328, but should run on all Arduinos with ATmega 168 or ATmega 328. ESP8266 or ESP32 ...

Hitachi’s HD44780 based 16×2 character LCD are very cheap and widely available, and is an essential part for any project that displays information. Using the LCD backpack, desired data can be ...

I2C protocol makes it easier to connect more ICs using only 2 wires SDA and SCL and allows communication between them at relatively low speed. The I2C bus or TWI (Two Wire Interface) allows a single ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a he… ...
