On this tutorial you see how to make a line following robot with the Zumo Chassis Kit, an Garagino (Arduino Uno compatible), two micro motors and insulation tape (to make the circuit). The circuit is inspired on Luigi Raceway circuit of game Mario Kart 64.

The image below shows the circuit with insulating tape (on the left) and the circuit from the game (on the right):…

Hello everyone,

This is more fun oriented project than something useful (or not) since ATmega328 was not designed for clock frequency above 20MHz (see datasheet). So, 30MHz is push it far from the limit. :)

Besides, I…

The folks over at Adafruit have been busy designing an LED matrix wristwatch for a while now. The circuit works great, but since this watch is powered by a coin cell battery, they’d really like to get the power consumption as low as possible. This means they needed a test rig to measure the consumption…

The user Young_Maker's (from Reddit) made a clock radio with arduino but its plays tunes from game Minecraft. The Arduino controls a LCD display. A RTC (to accurate time) and an uMp3 board were used to play random music from the game. The soundtrack is a way to gently wake up in the morning. But if time runs out, the boom of an explosion is played to make sure you’re not late for work.

A full Arduino MP3 player using a SD card and a MP3 module based on a chip from VLSI (VS1002d, VS1003 VS1053). The player includes a small amplifier and two speakers, making it a small Jukebox in the age of Ipods.

The project includes a…

Building an LED cube has been a project that we have always wanted to do, but the opportunity just never presented itsself. However, recently we were able to get our hands on an 8x8x8 LED kit (that's 512 LEDs!) which provides all the parts (95% of them) and instructions for building your own LED cube. The instructions weren't the greatest, so we went ahead and documented the entire process of building an 8x8x8 LED Cube. Hopefully it…

Electronics components are mostly bought from shops in India.But some times some components are unavailable or at remote places no such shops are available to the hobbyists.Here is the list of good electronics E-Shops with location and shipping costs.



Before that, this site is worth mentioning, for check the average cost of any electronic components.

This tutorial shows how to execute a .wav file from an SD memory card with Garagino, a breakout board for ATmega328, but you can use Arduino instead, and a USB/Serial FTDI converter, without any help of a shield! The. wav file is a sound file…

Maybe the smallest POV, made with ATTiny. This less than one ounce device is capable of display up to 7 different messages. Check it out: …

Rodot created this game with an Arduino. The project was well designed and integrates several components (accelerometer, TFT, etc) in a clever user interface. Check it out: …

Want to connect your arduino in the internet of things? The Arduino Cosm library is here for it. With the Cosm service, you can collect data an control your Arduino from the cloud. Check out the library: …

This project turns your arduino into a sos morse code sender. It sends the code using a LED connected to the digital pin 10. 

To build this project you will need:

• 1 Arduino board
• 1 LED
• 1 220ohm resistor

Build the circuit like the picture…

James Watson made a Rubik's cube solver with Arduino and a Python interface. You have to input the color combination and the Lego arm do the…

This is a project to test Li-ion batteries, found in several electronic devices nowadays, like mobile phones, tablets, cameras, etc.

For this project we will need:

• 1x Arduino
• 1x 6,9ohm resistor x 5Watts.

Build the following circuit:

Be careful! This is only…

On this tutorial, we will show how to use a Peltier with Arduino. The Peltier, or Thermoelectric coolers, are a device that can transfer heat from one side to another when a current is applied. You can use it as a heater or a cooler. This Peltier can be powered up to 15,4V and 7A.

To use the Peltier, you will need a…
