Hardware

Arduino Uno/Nano with gyroscope sensor MPU6050 and SSD1306 OLED 128x64 pixel display

Running on breadboard was not very stable for me over time (occassionally i2c-bus freezes). The same circuit soldered on board ran stable.

Appendix

Schematic

Used development environment

• Arduino IDE 2.3.4 or 1.8.19
• Arduino AVR Boards Version 1.8.6
• Adafruit GFX Library 1.11.11
• Adafruit SSD1306 2.5.13 (dont forget to uncomment #define SSD1306_NO_SPLASH in Adafruit_SSD1306.h to prevent the "Sketch too big" error)
• I2Cdev (from https://github.com/jrowberg/i2cdevlib)

FAQ

Can I use a SH1106 display instead of a SSD1306?

Official: No

The project was designed for a SSD1306 display.

To get the project working on a SH1106 display (as requested on https://www.youtube.com/watch?v=0g54CI1bC_A) there are some challenges to be resolved :

1. The library Adafruit_SSD1306 (I used v2.5.7) does not support the SH1106 display => Adafruit_SH110X is needed (I used v2.1.10)
2. The library Adafruit_SH110X seems to have a higher memory footprint then the Adafruit_SSD1306 library => Project would compile, but does not run (=Black screen)
3. Removing of display strings to reduce memory consumption in this special SH1106 version got the project working on a SH1106 display => Use a SSD1306 display for this project or be able to fix it yourself.
