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.

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

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.

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

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

The software library to calculate moon age, sunrise and sunset time.

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

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

Tutorial of Shift Register 74HC595, drivers like ULN2803, UDN2981, transistor BC327, making your designs more robust and reliable!

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

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

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!

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.

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

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.

A simple self contained Scalar Network Analyzer. It is used for testing and alignment of RF circuits, including amplifiers and filters.

Arduino Nano and Visuino: Convert Acceleration to Angle From Accelerometer and Gyroscope MPU6050 I2C Sensor - quick and easy.

Easily connect Arduino boards at a great distance over RS485 with Visuino.
