Improved version of the soldering iron controller for Hakko 907 iron. To simplify building the controller, LCD screen is implemented.

Goodbye calibration! Digitization of pH test paper! This is a pH meter that reads the color of the pH test paper.

Arduino Nano-based, password-protected AC Main Console.

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

FreeRTOS, simple, easy, robust, and optimised for Arduino IDE. Using FreeRTOS Semaphores to share and protect physical resources.

In this tutorial, I am going to talk about the PCF8574 8-bit GPIO port extender.

Get accurate readings for voltage using arduino.

Step by step approach is followed so that any hobbyist or design engineer can have a better understanding of the basic concepts.

Make a cheap variable power supply using the buck converter.

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

Need fast cheap laser rangefinder for your Arduino project? You can use a laser tape measure for this!

The Companion IC is a very cool looking Clock + Ohmmeter + Capacitance Meter + Diode Tester!

Make a Linux distribution that is focused on the development of Arduino and IoT. It's a Distro for Arduino.

Incubator that can be fabricated in a typical makerspace at a low cost while achieving the same performance as commercial units.

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

A study for a linear measuring device with Arduino and photoelectric rotary encoder.

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

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

It's an elevator with automatic doors. The code has two FSM, one for the motor that makes it go up and down and one for the automatic door.

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

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.
