In 2025 we are spoiled for choice when it comes to displays, with affordable LCDs, OLEDs, TFTs, and e-ink panels of all sizes only a few clicks away. But in decades past, such exotica were not on ...

It should also work on an Arduino Mega (AtMega2560), Gemma/AtTiny board, and most other AVR processors running on the Arduino framework. The Arduino Due, Arduino 101, and Teensy boards are not ...

4 and 19 pins are used to adjust the display contrast through a resistor. I use a 1 Mega Ohm variable resistor. Acceptable contrast ~270kOm.

This study uses Arduino Mega microcontroller as the main control, proximity sensor to detect the presence of glass, and the HC-SR04 ultrasonic sensor as a determinant of high water levels and an SD ...
