Controlling power to the system using alarms based on voltages!

AKA how to build your own laboratory vortexer without spending a lot of money.

Make your own mini oscilloscope at home. It’s simple and easy to do!

A small device that will help you sorting resistors without wasting time with their color code.

Analyze the responses of a bandpass Butterworth and Chebyshev1 filter deployed to an Arduino Nano from the Wolfram Language.

A Bluetooth multimeter capable of resistance, voltage, current and continuity measurement. Made with Arduino Nano.

Single tap, double tap, triple tap, four-tap, Hold, Single tap and hold.

Showcasing our spot welder, which is controlled by an Arduino Nano.

This micocontrollers laboratory is designed to speed up projects, and make easy and clean connections.

Did you run out of input pins? Don't worry, here is a solution without any shift registers.

A bit more accurate than __TIME__.

An Arduino Nano used as an IO expander on I2C for ESP8266. For example, add 8 digitals IO and 6 analog inputs.

Inexpensive to build but a very useful tool for every electronics laboratory.

Your personal universal electronics kit. More I/O pins. More devices. More distances. Remote wireless control. No bunch wires.

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

I wanted to make an electronics learning kit suitable for ages 12 and above. Nothing fancy like Elenco's kits but It can be done at home.

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

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

The soldering iron controller based on arduino that implements PID method to keep the temperature of the iron.
