For the first time ever, this site is now statically generated using hugo contnent templating system, I wish I’d done it years ago. For technology sites it really is like a breath of fresh air, as there is no more playing around trying to get code and techincal content into an online editor designed for WYSIWYG general purpose blog editing. For some time, I had kept the misconception that a CMS had to be dynamic; that was until I found I was spending considerable time trying to keep my Joomla system up to date and safe.

Wiring a 20x4 character display to an Arduino board

By dave on March 25, 2016

In this article I describe how to wire a 20x4 character display to an Arduino. I’m assuming you are using a regular 5V 8bit Arduino, if this is not the case this article will not work for you as you’ll need voltage level converters. Most character based LCD displays use the same wiring, but I can’t guarantee that all will be the same. If your display is the same it will look like the diagrams on this page and will have 16 pins.

Arduino Game library for 20x4 display

By dave on March 21, 2016

Here we discuss a game library that provides an easy way to write games with 20x4 parallel display and a few micro-switches. There is quite a lot of stuff going on in this library, so I’d like to start slow and build up. First, let’s start by taking a look at the parts needed to use this library: 20x4 display (other size will work too) 4k7 resistors (at least 6) 220R or 330R resistor for backlight Microswitches for joystick 1uF capacitor to smooth PWM Arduino and breadboard!
