Multi-touchscreen using the Wiimote
Johnny Chung Lee has come with a new and simple solution for a (multi) point screen. The idea is to track the IR point with an wiimote.
Look at Johnny Lee’s website for details..
Obiously, we from Labcoding.com love playing with the Wiimote, so we’re going to try Johnny’s experiment!
At first we need to download the software.
- Wiimote whiteboard
- Multitouch app ( if you build two IR pens, for one IR pen use, Wiimote Whiteboard)
- Direct-X sdk (it’s 426mb and only needed if you want to use the MultiTouch App)
Shopping list:
- 1 Wiimote
- 2 IR led (1.5V tolerant Led)
- 2 Small ‘press’ switch
- 2 (AA) battery
* for testing you can try a normal IR remote, but usually this blinks the IR signal, so it doesnt work that great!
Getting started:
First we need to make an IR led pen.
The scheme looks like this:
