Second degree equation solver with Arduino

This instuctable is about making sort of a calculator that enables the user by using an analog 12-digit keyboard and 4 buttons to input the a,b,c variables into a equation and get the solution for it if there is any.(well if u don't know what an second grade equation is probably u haven't been in high school, even though you can follow this post to learn about microcontrollers.) It can be a great electronic ...

Star Jar Geiger counter triggered LED decoration using Arduino

This instructable builds on top of the Geiger counter triggered LED decorations I made last year. This version powers the Geiger counter from the Arduino (itself now powered from a mains adaptor, so I no longer need to keep feeding them batteries) and the LEDs now fade in and out for a more gentle effect. What you'll need: A Geiger counter with pulse output (I'm using the Gieger counter from MightyOhm) A fe ...

Physical Computing with Arduino

Digital pins 1-7 are generally used as input pins and Digital pins 8-13 are used as output pins. Digital pins 9-11 can be used as analog output pins. That is, they can send they can send signal of variable voltage. 5/15/2012 Getting started with Arduino. I have skimmed through the "Getting Started with Arduino" and did the two main projects. The first project was about testing basic components/sensors (ligh ...

Arduino Calculator

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 that does the same thing for $2), It is really fun and adds a few skills to your inventory. Let me tell you ho ...

Keyless Entry / Arduino

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 the preset time limit. An override switch so the servo could be operated without the keypad. Some indication ...

DinoCalc Version 1.0

(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 HO ...

Multiplexing 7 Segment displays with Arduino and Shift Registers

In this instructable, I will be teaching the basics of multiplexing 7 segment displays using an Arduino and a couple of shift registers. This project is well suited for displaying numerical information or if you want to control a bunch of LEDs. For beginners, like me, I had no clue on how to tackle this project. But after trial and error and blood, sweat, and tears, I can say that I have a better understand ...

Scintillino – an Arduino-based quick&dirty scintillation counter

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 it sure works fine. It is a scintillation counter, no less and no more. In fact, the game was all about doi ...

Pixel Shipped Counter

Many times, we often use LCD as display equipment, from tiny temperature monitors to large industrial equipment. The funny thing in this project is that it combines two Red LED Matrices as display. You don't need other devices except Arduino to drive it. This project is build for to counting the shipped with wifi support. If you are big a fan of pixel art, this project is your type. :) PS: if you want get m ...

Button State Change Detection using Arduino

Once you've got a pushbutton working, you often want to do some action based on how many times the button is pushed. To do this, you need to know when the button changes state from off to on, and count how many times this change of state happens. This is called state change detection or edge detection. Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect t ...

Laser Triggered Countdown

This is a simple arduino based project that consists of a laser tripwire that, when triggered, will begin a countdown sequence on red, orange and green LEDs. I designed this to be an easy project for someone learning how arduinos work (like me). This is my first instructable so please bare with me :) (I'll apologies in advance the picture quality, my phone's camera isn't too great) Let's Go! Step 1: Materia ...
