I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the sheer variety ...

A 1.14 inch secondary display built around an ESP32, that receives video frames over Wi-Fi, and you could build your own for ...

There are plenty of SPI interface screens on the market, but few of them have the charm of the good old Nixie tube. [Tony] decided to whip up a simple three-Nixie module that could be addressed via ...

The moving-dot display has some benefits over the bar-graph display: It better indicates the location of a detected object in sonar and radar applications; it needs only one LED’s current-limiting ...

The project is utilizing cheap dot LEDs to create a big LED with an interface through SPI and can be expandable for multiple digits with only three wires for receiving data from any microcontroller ...

Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for the chip's power supply.

This file type includes high resolution graphics and schematics. When discussing displays, seven-segment displays and LCDs are among the first that come to mind. Each type has its pros and cons. But ...
