Measuring Acceleration ()
Continuing on from measuring speed, here we look at how to measure acceleration with a light gate. A video supporting this article is also available: If you've not built your light gate then see this guide. Also if your interested in measuring speed check this article out. What is acceleration? If you're accelerating then your speed is increasing. That is to.....

Measuring speed ()
In this article we look at using a light-gate to measure speed, if you've not already read the article about building a light gate then I suggest you start there first.  A video is also available showing the light gate build and measuring speed: What is speed? (Please skip this if you are up to speed with speed!) Speed is,.....

Building a light gate ()
A light gate a simply a device that can detect movement that occurs between a sender component and a receiver, usually the sender sends infra-red. You may think that they could be used as an intruder detector, and indeed you could use them for this purpose, but there are more elegant solutions to detecting intruders etc. A light gate is.....
Mis-adventures with a generic 128x128 colour TFT Display ()
In this article we look at driving a small 128x128 pixel 256K colour display using a ST7735 on-board driver chip. Turned out not to as straight forward as I would have wanted but got there in the end! http://www.xtronical.com/basics/displays/lcd-tft-colourcolor-display-128x128-pixel-1-44inch-3-7cm-st7735-driver/ Supporting video also available below.....
128x128 Colour LCD to Arduino ()
For an upcoming new project I wanted a colour (UK spelling) LCD screen (ideally OLED), 256x256 (or greater) resolution and nice and cheap. It was not an easy 2 minute task. There were no OLED screens offering what I wanted (that I could see at the time). So compromises were made, in the end I purchased a 128x128 pixel screen.....
