DIY Motion Sensor Alarm System

Are you constantly being scared when people sneak up behind your back? Do you have bad hearing and can't hear people approaching you? Do you want to just build a super fun Arduino project? If you answered yes to any of those questions, then this project is for you! I have a workbench in my basement that I use all of the time for homework and projects. The bench is right next to my furnace which is very loud ...

Build Your Own Arduino

Setting up an Arduino on a breadboard has become a process I have grown to love. Within a few minutes you can have a fully working Arduino platform to work with as you will see in this tutorial. There have been several occasions when I was at school and quickly put together one of these for testing some ideas for a project. Plus it is just looks so neat with all the components laid out over the breadboard. ...

Cheap working homemade arduino joystick

Hello everyone! Today I present you : Arduino Joystick! One day I was checking the inside of old joystick. System wasn't that hard to understand, so I thought of making my of system. The whole build is made only by me. I didn't check the internet pages about joysticks etc. What is it? It's a simple joystick type controller  that uses basic electronic parts and is easy to use even for beginners. Why should y ...

How to use an array with Arduino

This variation on the For Loop example shows how to use an array. An array is a variable with multiple parts. If you think of a variable as a cup that holds values, you might think of an array as an ice cube tray. It's like a series of linked cups, all of which can hold the same maximum value. The For Loop example shows you how to light up a series of LEDs attached to pins 2 through 7 of the Arduino, with c ...

DIY Binary Clock with Arduino

Yesterday I was going to start watching a movie, when me and my friend pedro decided to give up on the movie and build a binary clock. After sometime thinking on how to program it, we made it. It works beautifully, so I decided to show here how I’ve done. It may not be the easiest way to make it work, but that’s what we’ve done. Parts: - Arduino - 13x Leds (You choose the color) - 13x 220Ohms Resistors - 3x ...

Build your own Arduino – Bare Bone System

I’ve read through a lot of tutorials online to make an Arduino Clone on a breadboard, and some of them are great, but none of them really seem to have it all, so I’m going to attempt to bring it all together here and provide a tutorial with schematics, breadboard photos, Bill of Materials, and descriptions of all the materials. I’m going to provide the schematic for the system I am building here along with ...

DIY 3D Controller using an Arduino

Make a 3D interface using an six resistors, aluminum foil, and an Arduino. Take that, Wii. Update: a much more thorough explanation of this project is available from Make Magazine. It might be easier to follow their instructions, and I think their code is more up to date. The basic goal here was to make a 3D hand-position sensing system that most people can build, while still preserving some semblance of fu ...

Arduino String Addition Operator Code

You can add Strings together in a variety of ways. This is called concatenation and it results in the original String being longer by the length of the String or character array with which you concatenate it. The + operator allows you to combine a String with another String, with a constant character array, an ASCII representation of a constant or variable number, or a constant character.     // adding ...

Virtual Color Mixer using Arduino

This example demonstrates how to send multiple values from the Arduino board to the computer. The readings from three potentiometers are used to set the red, green, and blue components of the background color of a Processing sketch or Max/MSP patch. Software Required Processing or Max/MSP version 5 Circuit Connect analog sensors to analog input pins 0, 1, and 2.   This circuit uses three voltage divide ...
