Tonight we had our sixth hardware fun and games at C4DI. This time we were using the Arduino multicoloured LED and photosensor to make a device that could recognise colour. And it works. It uses some cunning software to shine different coloured lights on the object and measures the intensity of the light coming back each time. Peter did all the clever stuff, and you can find his notes here.
I also took along my 3Doodler which folks had great fun with.
We didn't think you could make things like this with it....
As I left there was lots of activity outside setting up stages for Hull Freedom Festival which is on over the weekend. If you are in Hull you really should go. We had a blast last year.
