How to establish UART communication between ATmega8 and Arduino Uno?

Here we are going to establish a communication between an ATmega8 microcontroller and Arduino Uno. The communication established here is UART (Universal Asynchronous Receiver Transmitter) type. It’s serial communication. By this serial communication data can be shared between two controllers, which is a required in various embedded system applications. In embedded systems we must have basic knowledge about ...

Clear polycarbonate enclosures using Arduino

So about a year ago I decided that I wanted to get into AVR microcontrollers. After ordering an AVR pocket programmer from Sparkfun , I soon realized that it was too delicate to be sitting on a workbench full of wire clippings. I knew I needed a small enclosure to put it in, but couldn't find anything I really liked. My final decision was to make my own. This instructable will explain the steps necessary to ...

Arduino Binary Die using arduino

After buying a Nanode (an Arduino-compatible board with ethernet built-in) last weekend, we've been trying to work it out by making a couple of simple examples, the 'Binary Dice' is the first one with input and outputs. A note, this code example is based on the one from the book Arduino: A Quick-Start Guide by Maik Schmidt. You'll need (other than the Nanode/Arduino board): 3 LEDs (ours were rated for 0.8mA ...

Arduino light seeker

First of all, I'm from Switzerland so please excuse my english mistakes. Here is one of my first little project I did with my Arduino Uno. It's is just a little light seeker. The servo turns towards the light. Step 1: The wiring Here is the exact wiring I used. The only difference is that I fixed the photoresistors on the servo (but I couldn't do it with the program) Also I used a 9V battery in the video, i ...

Wii Nunchuck as general purpose controller via Arduino board

Background: I made a self-balancing electric skateboard which is steered using a Wii Nunchuck by either using the thumb joystick on the top or by tilting it left or right, depending on which of the two buttons on the end are being pressed. A simplified self balancing board is described in the instructable here: www.instructables.com/id/Easy-build-self-balancing-skateboardrobotsegway-/ However people are ask ...

Arduino magnetic stripe decoder

This instructable shows how to use some freely available code, an arduino, and a standard magnetic stripe reader to scan and display the data stored on magnetic stripe cards such as credit cards, student IDs, etc. I was inspired to post this after reading the intro to magnetic stripe reading and Stripe Snoop that is found in MAKE magazine Volume 1. That tutorial details how to interface a stripe reader to a ...

EARTH SAVER: Autonomous Material Sorter using Arduino

This Arduino project was part of an Association of Mechanical Engineers (ASME) contest to create an Autonomous Material Sorter. The sorter was to sort four glass bottles, four plastic bottles, four Tin cans, and four Aluminum cans. There were requirements such as size of the bottles and size of the machine. The machine had to be able to sort the bottles and cans automatically after being started and had to ...
