One of the simplest ways to get a motor to turn in both directions is by using a double-pole, double-throw (DPDT) relay. Along with the relay, this hookup requires two transistors and two Stamp pins, one for on/off control and the other for direction control. The diagram below contains the schematic for this setup. The […]

Add an output device to a microcontroller board and program it to do something. Class syllabus:: http://academy.cba.mit.edu/classes/output_devices/index.html [what i learned /am learning] _ Relearned Arduino installation. _ Work with DC motors and H-Bridge IC with Arduino; and its general concepts. _ About the various Fab versions of Arduino and their features and differences: hello.arduino, fabkit2.0/fabduino,
Biking around cars can be a frightening thing, and staying visible at night is crucial for your safety. This tutorial will teach you how to make a custom LED Matrix Backpack that is much larger and brighter than traditional rear bike lights. Parts You’ll Need: Individually-addressable RGB LEDs Arduino Pro Mini (or any Arduino, this

The DJ Touch is a portable turntable touchscreen and interactive LED display. Our end goal was to produce a low cost touchscreen device, and demonstrate its application in a common consumer application. Out of an interest in electronic music, and with the knowledge of deejaying’s close roots to electronics, we decided to develop a touch
Summer Project: Arduino Scouting Robot Arduino Scouting Robot Part 1 * 12,9,5 volt power supply recharge it with a 12-volt charger keep power switch on to charge * 2 DC motors operate at 7.2V with a maximum current draw of 3 amps * 2 Digital Servos operate at 6V with a maximum current draw of
This robot that can solve a Rubik’s cube using Arduino. I learned how to solve a Rubiks cube last year, and I was also into Arduino, so eventually I ended up with an idea to make my own Rubik’s cube solver. Like many people searching for “Rubik’s Cube Solver” on Google, one of the first
Schematic Since the IR Sensor uses a light sensor, the schematic is very similar to that of the light sensor. The only difference is the addition of an IR LED and that the IR detector requires connection to 5V and ground. Breadboard Setup To setup the sensors you will need: 2x IR Detectors 2x IR

7-Segment LED Display is a very useful component, but also a very confusing and difficult piece to use for beginners. It won’t be difficult once you get it working for the first time. This is what you will get at the end of the tutorial (part one): It basically consists of 7 LEDs, (8 if include

The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. H-bridges can be built from scratch with bi-polar junction transistors (BJT) or with field effect transistors (FET), or can be purchased as an integrated unit in a single integrated circuit package such as
Servo Cable The continuous rotation servos that come with the BOE Shield-Bot have a 3-wire cable for connecting it to the power and controller. The black wire is the ground, the red wire is the power (positive) and the white wire (sometimes yellow, depending on the servo) is the signal wire. The signal wire is
