A programmable, portable, rechargeable power supply based on Arduino featuring an OLED display for viewing V.I.P. of projects/prototypes.

Measure rotation speed (RPM) with Optocoupler and Encoder disk and Arduino - Quick and Easy!

In this project, you can measure typically up to 48V. It is recommended to use Arduino digital voltmeter as “0-48V DVM”.

Control your Commodore C-64, reset C64, select Kernal, BASIC and Charset ROM, SD2IEC device#, info display.

Build a treasure chest or use an existing storage box, attach a push-button quadrature rotary encoder (endless spinning dial) and lets go!

Connect Matrix Keyboard using only 2 Arduino pins by using PCF8574/PCF8574A I2C GPIO - Quick and Easy!

On this simple tutorial, we will explore how to discover colors using an Arduino and the TCS 3200 sensor, displaying it on an LCD.

A homemade semi-automatic antenna tuner for HF controlled by an Arduino Nano.

This project is all about making a power inverter using arduino. The Inverter produces 220VAC from 12V battery.

Did your somewhat expensive ($50) soldering iron just die? Well then fix it with another one!
