Arduino Function Generator (Part 2)

Last time, we looked at some Arduino code that we could use to generate some square waves. The problem with the setup we’ve been looking at so far, is that we can only produce signals of one amplitude – equivalent to the HIGH logic level. In order to be able to produce any other waveforms […]

Arduino Function Generator (Part 1)

I was looking around for an interesting Arduino project, and I came up with the idea of making a function generator (also called a signal generator). The reason I picked a function generator is that it gives us the chance of playing with some interesting circuits – and some interesting code… Before we start with […]

Google Chromebook

Google & Samsung have announced the details of the first generation of Chromebooks – thin-client laptops running Google’s Chrome OS & reliant on a web connection for all of their capabilities. But can they succeed in a competitive market-place? The Chromebook is a nice idea. Thin-client (cloud) computing is becoming (if not yet the norm) […]
