Step by step on how to program a ATtiny85 microcontroller with Arduino Uno development board.

Using a phone as a makeshift GSM module.

In this tutorial, I will show you how to install the dark theme for your Arduino IDE for the reason of overexposure to the screen light.

Based on Blockly and BlocklyDuino, here's a multilingual enhanced version with supervision, upload, multi-level blocks, etc.

Arduino's great, but how in the world do you do two (or more) things at once on separate intervals? You need protothreading!

Simple Arduino Uno - ESP8266 software serial integration.

Replace all your IR remotes control with an Arduino.

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

Connect up to 10 buttons using a single interrupt.

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

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

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

Clock LCD display adjustable.

Training board for essential logic gates.

Use the IO Expander and Relay Expander with the Arduino to control up to 65,280 relays!

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

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

This Arduino-powered Web Oscilloscope supports trigger, and changing voltage/div, offset and time / div. It supports 6 channels.

The cheapest micro soldering station in the world, using a cheap USB soldering iron.

DIY Arduino hot air SMD rework station.

Log 6 analog and 8 digital pins from Arduino Uno simultaneously in Excel.

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.

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

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