We have written a tutorial for Rotary Encoders using a Microchip microcontroller but now would be a good time to make an Arduino UNO version. With a rotary encoder we have two square wave outputs (A and B) which are 90 degrees out of phase with each other. The number of pulses or steps generated […]

Arduino LEDs
Description In this tutorial you will set up and turn on a single LED. Note that this code can actually be executed with just the Arduino and no other components as in Figure 5. If you notice, next to pin 13 is a tiny LED on the board. If you execute the code below, you […]
Arduino Leonardo AVR Development Board
Arduino Leonardo AVR Development Board is a microcontroller board based on the Atmel ATmega32u4. It offers 20 digital IOs (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Arduino Leonardo differs […]
Android Phone Controlled Robot using Arduino
The Android phone that stays in your hand most of the time is useful in many other applications apart from Whatsapp, Facebook; appliances; monitor your health parameters. How it would be if it can control a Robot, which can assist in your daily work. With this project you can make a robot that can be […]
Servo powered peristaltic pump controlled by Arduino
This instructable shows you how to make a pump using a servo motor and an Arduino Uno to transfer small amounts of liquids. The pump is a peristaltic pump which consists mainly of a motor, flexible tubing and a circular pump casing. Two rollers attached to a turning rotor press the flexible tube to the […]
Use A Simple Cheap Webcam To Make DIY Microscope
This Project Is A Part Of The Afrimakers Event http://www.afrimakers.org/ Introduction We used a simple cheap webcam to make a microscope. In short, a small hack to the optics of a standard webcam with an adjustable focus-lens, allows to create video data, with a magnification of around 100 to 400x (depending on the model) at […]
Temperature Sensor v2.0
Overview This board allows you to use a thermistor to measure the temperature of something. It is designed to be used to measure things in the range of 100C – 300C, but with the proper calibration and resistors, it can be adapted to any temperature range you need (under 300C). If you need something that […]
PhysComp: Mid-term Project – Instagram TUI – prototyping the interactive elements using Arduino
The physical interface will consist of a 3×3 grid of push buttons that will correspond to a 3×3 grid of images in the Processing program. Instead of a creating a 2D array of variables to correspond to the buttons’ postions in the grid, each location in the grid will be assigned a number. Each push […]
Brushless DC (BLDC) motor with Arduino – Part 2. Circuit and Software
In this post I will describe the hardware and the software part of a project involving the use of BLDC (Brushless DC) motor salvaged from a broken XBox 360. This is a second installment in the series of posts related to Arduino and brushless DC motors. Please see the first part for a bit of […]
