Arduino Basics

Have you ever wondered if there was a way to store and retrieve data from a USB stick with an Arduino UNO? Most people choose SD cards to store their project data, but you may be surprised there IS a way! IC Station have a nice little module which allows you store and retrieve your Arduino (or other MCU) project data to a USB stick.   I am not too sure why USB storage is not widely used in Arduino projects? These modules are not expensive, they have been around for quite a while, and are relatively simple to use. You do not need any libraries to get them to work, however, I must say that documentation for this module is not that easy to find. This site and this document proved to be very useful in my endevour to get this module working, and I hope my tutorial below will help you get started and bridge some of the information gaps.   The...

E-Paper (or Electronic paper) is a display technology that mimics the appearance of ordinary ink on paper. E-paper displays do not emit light, rather they reflect light, thus making them much more comfortable to read and provide a wider viewing angle than most light emitting displays ( source: Wikipedia ). I printed something to an E-paper display, unplugged it, and could still read the message clearly months later. These E-paper displays are great for showing information that is static for long periods. You only need to provide power when the data or information needs updating. Barcodes are used everywhere, and one of the simplest Barcodes to generate is the Code 39 format (also known as Code 3 of 9). I used an E-paper shield and E-paper module to display a number in this barcode format. I then tested it with a Barcode reader and it worked perfectly. This tutorial will show you how to send a number t...
