Build a treasure chest or use an existing storage box, attach a push-button quadrature rotary encoder (endless spinning dial) and lets go!
In this project, I am going to make a LAN cable tester with just a few basic electronics components. It cost me just a bit over $3.
I built the right and left mouse buttons with wall switches.
Use FreeRTOS (simple, easy, robust, & optimised for the Arduino IDE) to reduce the power required for battery or low power applications.
Easily connect Arduino boards at a great distance over RS485 with Visuino.
ESP8266 Arduino Programming Tutorial - Easy to learn, step by step.
Using the built-in Arduino EEPROM to save and restore values - Quick and Easy.
