Paperino, The ePaper Display Shield

ePaper displays (EPDs) are becoming a trend in application, just like the display used in Amazon Kindle, for their low power consumption due to the to the underlying ‘bistable’ display technology. These displays can continue to show information without any power at all. It is only required while updating the display with new information, otherwise there won’t be any power consumption. Providing such revolut ...

Arduino RFID Keycard Access

Motivation Keys are so last century, and now that you can easily replicate a physical key just by snagging a photo it might be time to upgrade our locks! This project outlines a framework for you to get started implementing your own unique locking mechanisms. In this project you'll authenticate individuals using Mifare Classic RFID Tag UIDs and display a message on the LCD screen. Once you get this working ...

How to Set Up and Program an LCD Display on an Arduino

In this tutorial, I’ll explain how to set up an LCD on an Arduino and show you all the different ways you can program it. I’ll show you how to print text, scroll text, make custom characters, blink text, and position text. They’re great for any project that outputs data, and they can make your project a lot more interesting and interactive. The display I’m using is a 16×2 LCD display that I bought for about ...

Replacing a dead iPhone battery

About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a "this accessory may not be supported" message appeared on-screen; when I unplugged and re-plugged the iPhone to the charger, it didn't reappear, so I didn't think anything more of it ... until a half hour later, when the iPhone again alerted me, this ti ...

How to Interface Flux Sensor

This tutorial is going to teach you the basics on using Flux Sensor of 2.2 inches. Step 1: Introduction Description: It is a flex sensor which is 2.2 inches in length. This sensor works by bending the sensor itself. As the sensor is being flexed or bent, the resistance across the sensor increases. The greater the angle of bending, the greater the resistance. This can be tested with multimeter. The resistanc ...

Scale Speedometer

What is this ? This project is a "real size"  speedometer for miniature trains, cars and anything you wish to measure. It can calculate the speed of the object between 2 measuring points along the track (or road) by counting milliseconds between passages at the  start and end gates.  If you enter the distance between those gates  (in dm) and the used scale  (ex. H0 = 1:87) in to the Arduino, it will calcula ...

A new form of retina implant returns sight to the blind

What if you could cure blindness as easily as turning on the lights? That’s what one doctor and his team are hoping to achieve with a clinical trial that uses a new form of retina implant to return sight to patients who have lost the ability to see. And for one of the six patients, it’s been a pretty incredible journey. Rhian Lewis was just a toddler when her parents noticed she had trouble seeing in the da ...

Automatic blind hooked up to existing projector screen using Arduino

Hello my name is Chipsy, I'm French, reading instructables since at least 2 years, it is the first entry i make on this website. Why i made this project : I have a small homecinema system in my living room, with a projector and a commercial motorized projector screen. I have a big mirror on the left wall, it makes the room brigther, but when watching a movie you want a dark room, and we could see reflection ...

Arduino Watch with Nokia 3110 screen

My goal for this project is to make a watch with selectable dials, stopwatch and millidays. This idea started with an Aprils fools prank about metric-time. (http://www.youtube.com/watch?v=K35xG1buyFA) First I wanted to make a metric clock but soon this idea evolved from a metric watch into an open course watch. I knew that it would be hard (or impossible) to make the watch small enough to really wear, but I ...

Android & Arduino Controlled Projector Screen

This is my first time using Arduino, or any microcontroller. I'm glad it worked out so well but my wife may not be, due to the stacks of microcontrollers that will being showing up on our doorstep soon for future projects. Any feedback or questions are welcome, as are votes in the Arduino Contest. Why (Problem) I love watching sports, my family loves watching sports, and we all love cheering on our local co ...
