Arduino Weather Station

How cool would it be to have your own Arduino weather station right in your backyard? Sounds fun? Geeky? Having your own weather station means that you don’t need any more inaccurate results from the weather channel! You can even log the data and play around with it. Set mood lighting according to the weather? Why not? This tutorial will get you kick-started with your own DIY Weather Box to chart out local ...

Create a Christmas Light Show with Arduino

The Christmas light show with Arduino is a project that controls a number of lights according to a song in sync with the music. It can be used to control stage lights and fog machines (that don’t have DMX) with a computer to achieve wonderful synchronization for performances on stage, which is not always possible with manual lighting control consoles. During last year’s holidays, I was watching videos of Ch ...

Extract DNA at Home with a 3D Printed Centrifuge

Biotechnology is powerful, but only for those with the tools to experiment with and utilize it. The DIYbio movement seeks to put the tools and techniques used in well-funded laboratories around the world into the hands of ordinary people who have an interest but not the means to investigate biology. One of these tools is the centrifuge. Centrifuges come in many shapes and sizes to fit a wide variety of labo ...

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 ...
