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 project demonstrates how to control an 8x8 LED dot matrix display using an Arduino and the LedControl library. The code initializes the matrix, displays a predefined pattern, and refreshes it ...

The circuit interfaces a display that features four 5-by-5 dot-matrix characters by using the display’s serial peripheral interface and a programmable system on a chip (PSoC). The SPI reduces ...

Such is the case with this marble-raising dot-matrix alphanumeric display. But it’s pretty cool, so we’ll give it a shot.

According to the characteristics of nano-diamond, scanning and display program is designed and written in assembly language. 16×16 Chinese characters dot matrix are displayed on LED, which verifies ...
