This guide will explain the basics of controlling multiple 7 segment displays using an Arduino and a couple of shift registers. This project is ideal for displaying numerical data or managing a set of LEDs. As a beginner, like me, I had no clue on how to tackle this task. After trying out different methods […]

Arduino Project – The distance calculator I have been playing with Arduino (micro-controller) for about 2 years now and I am becoming more and more passionate about circuits. For those who are not aware of Arduino, check out my article “Arduino – A Guide for Beginners“. Recently, I was testing some new components that I
(Arduino Pro Mini Protoboard Version) Latest Release: http://code.google.com/p/dinocalc/ Development: https://github.com/WeaselJones/DinoCalc This is a calculator without a LCD that tells you if your math answer is right or wrong, without giving you the answer. This instructable will show you how to make this simple math checking calculator using “off-the-shelf” items. [UPDATE: A TUTORIAL SHOWING HOW TO
This project brings back the old time Analog VU Meter, with the added functionality of a neat looking clock! When you turn off your music the meters automatically swing into to clock mode. Behind it all is the popular and easy to use Arduino. This is my submission for the Make-to-Learn Youth Contest: What did
In this Instructable I will show you how to make an Arduino calculator that is just as good as any other calculator (well… sort of). Even though it’s probably not practical due to it’s size, repetitive use of the equals button (due to the lack of keys), and cost (You can probably buy a calculator
Keyless Entry System Enter the correct code into the keypad and the servo will unlock the door. Enter the incorrect code and Sorry you stay out. There was a couple of stipulations i wanted in my Keyless Entry system: Helper Light. A light that would come on whenever a key was pressed. Then off after
A key factor when building a pinewood derby car is its weight. The Boy Scouts of America and other organizations specify a weight of no more than 5 ounces. To improve performance many builders will add as much weight (mass) as possible up to that maximum allowable weight limit. What is often overlooked is the

By: Sonya Singh Computer Engineering Step 1: Project Overview Have you ever dreamed of building a 2-bit adder calculator, which can display the results in both binary and decimal? Well, look no further – Through this guide, your dreams have finally come true! Not only will you learn to build the adder, but you’ll also
Have you ever wondered about the radiation levels around you? Well today you can build your very own detector that measures ionizing radiation and displays data in real-time on an LCD (and also your computer if you want). The visual design, as seen below, is perhaps a tad short of a Red Dot Award, but

Hey, welcome to my first instructable where I will be helping you create a calculator. It’s basically made up of a 16×2 LCD, with an Arduino UNO that you can use in order to make quick calculations from far distances. I know, it doesn’t make sense right, well I did not have a keypad but
