1×10³²⁴ things to do with a chipKIT™ Lenny and a QuickIO. No. 2: Virtual Mouse.

LennyQuickIOSmall.pngNumber two in my series of what to do with a Lenny and QuickIO.

How about a mouse? Yeah, a mouse. Honest 🙂

Well, maybe not an actual mouse, but maybe make it control the mouse pointer in an “almost” usable way…?

The two potentiometers on the QuickIO could control the mouse position, and the buttons can be the mouse buttons for clicking, etc. That should work.

1×10³²⁴ things to do with a chipKIT™ Lenny and a QuickIO. No. 1: Autoclicker.

LennyQuickIOSmall.pngThis is the first part of a new series entitled “1×10³²⁴ things to do with a chipKIT™ Lenny and a QuickIO“. In it, I’m going to be exploring some of the cool things you could do in just a matter of seconds using the two boards combined.

This first one is an Autoclicker.

Vacuum Fluorescent Displays on Arduino

Watch the accompanying YouTube video here.

Vacuum Fluorescent Displays are probably one of the coolest displays of all time. Certainly one of the most popular of recent history. Developed in 1959 by Philips they have endured right through to modern times. You can even still find them in current consumer electronics.

Adding An OLED To My Computer

As part of my work I end up with hundreds of small TFT and OLED displays scattered around doing nothing. One of them, the PG25664CG OLED screen (16 shades of green) I figured would be about the same size and shape as a 5.25″ drive bay in a PC.

And guess what? I was right! An absolutely (well, a couple of mm out) perfect match. So I decided I should build one into my computer to display stuff. No idea what stuff yet, but stuff anyway. I’ll decide later when I have written the software for it all. Continue reading

Splitting Up Text in C

A common question I often find is:

How can I split this incoming data into parts?

It’s especially asked in conjunction with reading data through serial. So I thought I’d introduce you to two completely different approaches, each with benefits and drawbacks depending on the kind of data you are splitting.

What Exactly is a GPIO Pin?

I was hoping to make this the topic of my first ever video tutorial, but I still haven’t got round to cleaning my desk of all the junk and setting up a holder for my phone to use as a camera. Plus I am suffering from a bad cold right now and sound awful. So text it is.

I’d like to help you get to know exactly what a digital IO pin of an Arduino actually is and how it works. Many questions I come across along the lines of “How does this work”, or “Why do you need to do this”, or similar, can be answered easily if you know exactly what goes on inside an IO pin.
