Build a Controllable Coffee Roaster from an Air Popcorn Popper

Home Automation Projects / By Ibrar Ayyub

I have a passion for coffee. I also have a passion for electrical engineering. Why not combine them? This Instructable describes how I transformed a hot air popcorn popper into a completely controllable coffee roaster! Follow these instructions to re-purpose and hack your West Bend Poppery Popcorn Popper into this coffee roaster! ———————————————————————————————– The extraction

ESM – External Serial Monitor Using Arduino

LCD Projects / By Ibrar Ayyub

Sometimes I needed an external serial monitor like the Serial Monitor in the Arduino Editor, to see what is going on. So I made one. The first picture shows an example how could be it designed. For the ESM I used an Atmel Atmega328 (based on the Arduino-Board) because it have an internal SRAM with

Augmented Water using arduino

Home Automation Projects / By Ibrar Ayyub

The Augmented Water device helps you save water by turning red after one Liter. The device, built by @tamberg during a water hackathon, is made from an Arduino, a flow sensor and coloured LED pixels.

DC Motor Control Using an H-Bridge using arduino

Motor Projects / By Ibrar Ayyub

Overview In this tutorial, you’ll learn how to control a DC motor’s direction using an H-bridge. To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit. There are many different models and brands of

Digital Clock Design Using Arduino

Clock – Timer Projects / By Ibrar Ayyub

Introduction This design project utilizes an Arduino MEGA2560 with an ATMEGA1280-16AU microcontroller to create a digital clock. The clock will be able to save time when disconnected from power, and it can be powered from a USB connection or from the wall outlet. The clock displays the hours, minutes, and seconds with an AM/PM indicator.

AVR Programming Tutorial

Arduino Programmer Projects / By Ibrar Ayyub

This tutorial introduces programming for AVR microcontrollers. It uses the ATmega328p found on Arduino boards, but works with straight AVR C and a bare microcontroller. It covers the basic information you need to get started, whether or not you’ve used Arduino or other microcontrollers previously. Why would you want to learn AVR programming (instead of,

Heat-Seeking Desk Fan (using Arduino)

Home Automation Projects / By Ibrar Ayyub

Summary: The following is a step by step guide on how to make a Heat-Seeking Desk Fan from an Arduino microcontroller, a computer fan, a servo, and an infrared temperature sensor. The device scans the room periodically, automatically pointing itself in the hottest direction (ideally towards a person). This is a working proof-of-concept model, but it

Make a Desktop Tamagotchi Using Arduino

Game – Entertainment Projects, LED Projects / By Ibrar Ayyub

One day I was sitting behind my desk at work and I got that weird need to build something, after looking around for a bit I got my eye on an LED matrix and that sparked an idea in my head : “I WANNA MAKE A TAMAGOTCHI”. So for those of you that don’t know

Microcontrollers: The Basics

Development Board – Kits Projects / By Ibrar Ayyub

Different kinds of computers are designed for different purposes. The computer at the heart of your laptop is optimized for different puprposes than the one in your phone or the one in your mouse. The simplest computers are those that are designed to take inout from the phyiscal world and control output devices in the

Arduino Lilypad Slipper Automatic Foot Massager

Home Automation Projects, Medical – Health based Projects / By Ibrar Ayyub

I made a little automatic slipper foot massager with the Lilypad Arduino and some of the Lilypad Vibe Boards for the actual massager. The sensor it uses is a Lilypad Accelerometer that I’m only using as a basic tilt sensor. Essentially it detects when the slipper is in a more vertical position (like when you
