Once upon a time, if you wanted to generate some waveforms, you needed to buy an expensive off-the-shelf function generator or whip up a big pile of analog electronics. Not so today, when you can grab a fast microcontroller off the shelf and have it squirt out whatever fancy waves you might desire. That’s just what […]

Introduction Arduino represents an open-source electronics prototyping platform built upon versatile and user-friendly hardware and software components. Its purpose is to cater to artists, designers, hobbyists, and individuals keen on crafting interactive objects or environments. Getting Started with Arduino UNO The Arduino platform offers a variety of board options to choose from. For beginners, you

I have been designing and building a robot. It got to the stage where it was time to do a head for it, but before I did the head I needed to design some Eyes for it using the Nokia screens found cheaply on eBay. There was certain criteria I wanted this project to meet. One

This project it’s a new time-lapse tripod or panning with two axis that works with an arduino protoboard. Everyone will be able to create their own time-lapse trajectory without need to check it. With the arduino code we’ll can change the value for the movement degrees that we want. Step 1: Bill of Materials –

As EDN’s Design Ideas editor, I see a range of design submissions, from good, to not so good. A recent DI I turned down for several reasons included a high-side current sense circuit with implementation problems. This got me thinking about the different ways to accomplish current sensing on a voltage rail. At their heart,
Sensing current on the high side Continue Reading
Many AA or AAA battery chargers charge batteries in pairs, but plenty of devices use 1 or 3 batteries, meaning that some of your batteries get overcharged and some get undercharged. NiCd and NiMH batteries also benefit from an occasional full discharge, which most normal battery chargers won’t do. If you’re anything like me you’ll
