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 […]
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 […]
The Bass Master 3000 is a game that I built for a work carnival along with a small and very talented team of co-workers. I’ve seen this type of game on the net, but I wanted to kick it up a notch with some Arduino powered sensors that would trigger lights and sound when someone […]
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 […]
This is what came out of my attempt at combining some of my favorite tools and themes…Grasshopper, 3D printing, kinetic motion, and linguistics. I put these gloves on my friends, asked them to tell me a story, and used Grasshopper to record the data from their hand gestures. While these gloves are far from precise […]
This is a very easy project. Here is the result I won’t go into too much detail how each part works, because I have written some information on my blog. But you should be able to make it work with the information given on this instructable. Step 1: Prepare RGB LED strip The RGB LEDs […]
Overview As enthusiasts of audio, we aimed to use our recent understanding of microcontrollers to create an exciting consumer gadget. Our project is a drum machine that functions as a step sequencer. The user can create a 16-step percussion sequence with various percussion instruments on six separate tracks. The user switches between various music tracks […]
LED Cubes are awesome. The first one I created was a 8x8x8 blue led cube. It still works like a charm. But being able to display every colour in the spectrum is much more spectacular. Let’s start with a small and simple 4x4x4 RGB LED Cube. Step 1: Watch part 1 of the video series! […]
This simple device sits on your desk at work, ready to give you fist bumps throughout the day as you need them. A 3D printed “fist” is moved by a servo attached to a rack and pinion mechanism. An ultrasonic range finder detects when you place your hand near it, and an Arduino Uno controls […]
