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.

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

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

A bit more accurate than __TIME__.

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

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

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

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

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

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

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

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

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

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

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.

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