This project combines two Arduino Uno boards: one as a master and the other as a slave. The master Arduino handles the LCD display and temperature monitoring using a DHT22 sensor. The slave Arduino ...

This is a weekend project naive arduino library made for HD44780 controller based lcd's. It abstracts the complexity of directly interacting with the LCD's hardware, making it simple to display text, ...

Today, I'm thrilled to guide you through the steps to create your very own 32x8 compact LED matrix, driven by an Arduino Nano. For a double fun, the used LEDs are purple. Let's dive right into it!

The Graphic Dot Matrix LCD Module consisting of a super large area twisted nematic LCD of 64 x 320 dots and its driving circuit is described. This new graphic module can display not only graphic ...

Thus, you have control over all the 64 LEDs by connecting the module just through three wires to microcontrollers like Arduino, NodeMCU, ESP32, STM32, etc. Fig. 2: MAX7219 LED dot-matrix 4-in-1 ...

[August 22, 2006] Particularly viable for headsets, weigh scales, utility meters, battery-driven products, and large displays, the EM6110 bitmap controller/driver for dot-matrix ...
