A general tutorial on installing Arduino bootloader on ATmega8 AVR microcontroller and programming it using Arduino IDE.

Sketch of transistor tester project from Karl-Heinz Kübbeler, so it's much simpler to study, modify, verify and upload to an Arduino.

This code performs FFT with good accuracy.

In this tutorial I will explain how to use the TIMER0 of Arduino

Arduino is used to measure frequency and duty cycle of pulses and display them on LCD.

Connect up to 10 buttons using a single interrupt.

Everyone uses a 16MHz oscillator for a homemade Arduino, but did you know that ATmega328 can run without it?

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

I found the Arduino Leonardo to be a great way to manage my CNC machine with little programming effort.

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

Thermistor as thermometer.

When it sees you, it won't stop following!

Get not only 5 volts but also 9, 12 volts (18 Watts max) out of any QC-compatible charger/power bank for supplying power hungry projects.

Measure CO2 levels.

Introduction to watchdog timer in microcontroller

A simple to build, but very sensitive electromagnetic field detector.

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

With this simple circuit the analog output of Arduino Due start from zero
