7-Segment Display

A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. Seven-segment displays are widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information.

ID Chicken Eggs with Thermal Images, ML, and Cellular IoT

“In part one of a two-part project, we display thermal images on a TFT display, save them to flash, all to build an ML model w/ SMS alerts! One thing they don’t tell you about raising chickens in the …

Number Maze Game

“This is a handheld game that displays a 4x4 matrix of numbers representing a logic maze, and you have to solve the maze by pressing the buttons Your position in the maze is shown by the decimal point, and you …

The Arduino Launch Control System (LCS)

“The Arduino Launch Control System is a model rocket launch controller for a single rod launch pad. This was the first Arduino rocketry project that I wanted to design and build, having just started into learning about electronics and the …

General Purpose Relay Timer
