LED displays are commonly packaged as arrays of LEDs organized in rows with shared positive terminals and columns with shared negative terminals, or vice versa. Here is a standard illustration, along with its diagram: These exhibits can be very useful. To control a matrix, you connect its rows and columns to your microcontroller. The columns […]

Build a robot that responds to electrical activity in your brain—it’s easy and fun. If you’re familiar with Arduino and have basic mechanical building skills, this book will show you how to construct a robot that plays sounds, blinks lights, and reacts to signals from an affordable electroencephalography (EEG) headband. Concentrate and the robot will

This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Creating emergent patterns that can be converted into sounds fascinates me. So this is my first experiment in building an arduino platform for creating such patterns. This version uses a Gameduino as its

This is a tutorial on how to use 123D Catch to get a 3D scan of your whole body. Once you have the scan or “catch” the tutorial will take you through a technique to clean it up and manipulate it ready for 123D Make. The tutorial will go through how to slice the model
A note on what this document covers The key addition to the wealth of online information about pulse counting is the method of counting pulses from multiple sources (up to 12) using continuous sampling and direct port manipulation in an Arduino sketch instead of interrupt-based counting. When tallying pulses from one or two pulse output
Reading pulses from meters with pulse outputs.. using arduino Continue Reading
My close friend, who works as a teacher, was conducting quizzes in her class that involved students competing to answer questions. This caused some students to complain about not getting a chance to answer even though they had raised their hands first. I chose to gift her with a buzzer similar to those used on
The 16×2 LCD And Keypad Shield is easy to use as it works seamlessly with the Arduino “LiquidCrystal” library. With just a few lines of code, you can set up the LCD and show messages on it. Additionally, you have the option to create more complex projects like displaying menu items and using buttons to

I’ve been in possession of an Arduino Duemilanove for a couple of weeks. If you are unfamiliar with the Arduino, it is defined as “a platform for creating electronics prototypes using adaptable, user-friendly hardware and software”. The setup consists of a small microcontroller, a USB port for programming on a computer, a power socket for
DIY wattmeter with an Arduino Measuring power and energy using regular multimeters can be challenging or even unfeasible at times. In order to conduct such a precise and reliable measurement, a specific wattmeter is necessary. Due to their high cost, an alternative option is introduced in the form of a homemade wattmeter using an Arduino
