Stepper motors are not smooth – they move in “steps”. Different motors have a different number of steps to make one complete rotation. You use software to step the motor forward or backward at different speeds. There are two kinds of stepper motor bipolar and unipolar – Unipolar will have five or six cables coming […]

The aim of this project is to create a setup to capture the image of a falling object or any object in motion at a precise time using a DSLR and Arduino microcontroller. It can be done in many different ways, but the method I tried is illustrated below. Figure 1: Schematic of the setup

A Binary Clock! I was recently looking at some binary clocks and I felt like Why not? I have everything to make one and I don’t have a clock in my room. So I decided to build one and here it is. Hope you Like it and maybe build your own. It’s a cool project

Hi all, For a project, I was looking for a cheap solution to send data from an Arduino to an other one. The serial port was already taken, and my transmission (unidirectional) needed to be wireless. My researches has brought me to discover these kinds of radio modules (433MHz). They were available on the net,

Hey guys! Since I’ve got my servos, I’ve had two that I set aside for hacking. So, coming to my favorite website for help, I was sorely disappointed when I couldn’t seem to find any instructables on how to mod a micro servo. After viewing a few, I went to my workbench and got to

LEDs are great. But with any project there comes a point where flashing is simply not enough. For these cases an RGB (Red, Green, BLue) LED is the answer. With an RGB LED you’ll be able to produce any colour glow your heart desires. At first using an RGB LED seems quite complex, but it

The Darkness Map encompasses both data collection and visualization of nighttime light levels. You can add to the map by downloading the app for iPhone or Android, but you can also contribute data by creating your own data collection device. This tutorial will cover how to build an Arduino powered data logger with a light

UPDATE FEB 2012: This guide is featured on Adafruit’s blog http://www.adafruit.com/blog/2012/02/14/arduino-based-line-follower-robot/ This is Faz3a II, my first line-following robot, which I also hope to use for maze-solving. I used the Arduino Uno, Adafruit motor shield, Pololu’s QTR-8RC line sensors and motors. You can build a cheaper and lighter version of this robot using the Atmel

Introducing the RainBoard: A simple RGB LED Rainbow fader using an Arduino Uno and a few simple components. Believe it or not, we will control 45-channels of RGB LEDs at 32 brightness levels using only 3 digital pins from the Arduino! How is this possible you ask? By using two magic concepts: Shift Registers, and
