Arduino Ping
The Ping is an ultrasonic range finder from Parallax. It detects the distance of the closest object in front of the sensor (from 2 cm up to 3m). It works by sen...
Arduino Midi
MIDI, the Musical Instrument Digital Interface, is a useful protocol for controlling synthesizers, sequencers, and other musical devices. MIDI devices are gener...
Arduino Master Reader
In some situations, it can be helpful to set up two (or more!) Arduino boards to share information with each other. In this example, two Arduinos are programmed...
Arduino Liquid Crystal Cursor
The Liquid Crystal Library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can...
Arduino Knock
A piezo is an electronic device that generates a voltage when it`s physically deformed by a vibration, sound wave, or mechanical strain. Similarly, when you put...
Arduino Calibration
This example demonstrates one techinque for calibrating sensor input. The Arduino takes sensor readings for five seconds during the startup, and tracks the high...
Arduino Barometric Pressure WebServer
This example shows how to use SPI communications to read data from a SCP1000 Barometric Pressure sensor, and how to then post that data to the web by using your...
Arduino BarGraph
The bar graph - a series of LEDs in a line, such as you see on an audio display - is a common hardware display for analog sensors. It`s made up of a series of L...
Arduino Analog WriteMega
Connect the longer, positive legs of (anodes) 12 LEDs to digital pins 2-13 through 220 ohm current limiting resistors. Connect the shorter, negative legs (catho...
Arduino Analog Input
A potentiometer is a simple knob that provides a variable resistance, which you can read into the Arduino board as an analog value. In this example, you`ll conn...

Your Duino Starter
This manual will show you how to use each of the components in the kit, and give you software Sketch examples for each one. Then you can combine some components...
Arduino Power
Having your Arduino control higher-power devices like lights, motors, pumps, doors, and many more is one of the most interesting and useful applications you may...
Arduino How to control a Servo
In this one, servo is programmed to be controlled by two buttons, one turns servo to the left and the other one turns it to the right. When the servo is turning...
Arduino Digital audio player
So far in this series we`ve had a diverse look at how Arduino can interact with a range of real-world devices from servo motors to ultrasonic range finders TVs ...
Arduino TV weather channel
So far the idea has been to show you how the Arduino Uno board and its Atmel ATMEGA328P microcontroller can interact fairly simply with the outside world. This ...
Arduino Build LED weather station
In Part 2 of our Arduino masterclass we`re cracking on to build a weather station that measures temperature in degrees Celsius and relative humidity as a percen...
