Encoder with button and set limits. When the extreme value is reached, the next transaction continues counting from the extreme opposite value. For example, with limits from 1 to 4, when the value of 4 is reached, continues counting from 1 and vice versa.
Arduino library for OLED displays driven by the SH1106G chip. Communication via I2C. Wraps Adafruit_SH130x (https://github.com/adafruit/Adafruit_SH110x). N.B. UNTESTED!
Arduino library for OLED displays driven by the SH1107 chip. Communication via I2C. Wraps Adafruit_SH130x (https://github.com/adafruit/Adafruit_SH110x). Tested using a Pimoroni Mono OLED Breakout (1.12" 128x128 pixels) and ESP32.
Save data (byte, number and string data types) to the non-volatile storage (NVS) of the ESP32. Wrapper for the ESP32 Preferences library (https://github.com/espressif/arduino-esp32/tree/master/libraries/Preferences).
