Stepper Motor drive from Arduino

Stepper Motor drive from Arduino In this tutorial we will show you how to connect a bipolar stepper motor to an Arduino Uno board. The stepper motor we are using is the Sparkfun Stepper Motor but you can use any other 4-wire bipolar stepper motor. Because a stepper motor draws a higher current than the Arduino processor can handle we are going to use a Quad half H-Bridge chip to control the stepper motor. T ...

How to: Use Arduino to Generate Glitchy Audio VGA Visuals

This post is a guide for people that are interested in my previous posts about dual monitor VGA hacking (see 1, 2 and 3). You will need: • A laptop or a computer with a VGA output • A breadboard (optional) and some wires or a strip board for soldering • Wire and breadboard jumpers (optional) • 2 female VGA connectors • 1 male VGA connector • up to 3 lots of 15x1 or 15x2 pin headers (optional) • An Arduino, ...

Hacked Pan and Tilt Camera Mount

So my sister managed to break a pan and tilt camera mount and naturally thought daddy can fix this. After sitting on my dads workshop bench for a while he had a go at it and couldn't work out how to fix it so it was passed on to me as broken. So I decided to hang the current circuit board and lets make this thing arduino compatible and while I am at it lets make it wireless :-) In preparation for this I had ...

3dpBurner – A 3D printed laser cutter/engraver

3dpBurner is an open source laser cutter/engraver. It is created with the same concept as RepRap, using 3D printed parts and some easy to find "vitamins" (non printed hardware). I tried to make it as cheap as possible, by using cheap electronics and a "low power" laser (a laser diode). The X/Y working area is fully customisable and the max working object height is up to 50-60mm. The cutter/engraver basicall ...

Adafruit Arduino Motor Shield Build

Overview The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features. The shield is T ...

How to make fist pumping with LED animation using Arduino

It's to make a fist pumping LED controller. What is it? Have you noticed yourself fist pumping to the music at a party or a club? That's exactly for that. You would wear a band with a accelerometer/gyro mounted. As you move your hand around the air, the movement will trigger a light board and create different LED patterns based on the position of your hand. This will be a fun project. Step 1: What you need ...

Automatic blind hooked up to existing projector screen using Arduino

Hello my name is Chipsy, I'm French, reading instructables since at least 2 years, it is the first entry i make on this website. Why i made this project : I have a small homecinema system in my living room, with a projector and a commercial motorized projector screen. I have a big mirror on the left wall, it makes the room brigther, but when watching a movie you want a dark room, and we could see reflection ...
