Show system temperature on a mini i2c (9E6018A0) screen via Arduino Nano

Posted on 23 Apr 2021 - 15:45
Introduction This is a project showing How to wire the I2C display to an Arduino How to retrieve the CPU temperature (or other values) from Linux’s sysfs How to use the RS232 library by wjwwood How to connect to the Arduino Nano and send data How to receive data in Arduino How to display data through the nice graphics library by Adafruit —— (also how to scribble with that library) We will build a minimal C++ console application that retrieves a temperature value from Linux’s sysfs and sends it to a serial port.
