Topic: LEDs as sensors, newbie needs help! (Read 4220 times) previous topic - next topic


Hi everyone, I have been unactive due to sickness (someone actually coughed in my face and it was downhill from there).

Thanks for the advice (and to dhenry!) I'm on it.

I've had a bit of fun with a 10 segment display (http://www.maplin.co.uk/10-segment-display-2128) and Mike's code, giving ok results.

What I need to do now is be able to locate something the shape of a ping-pong ball falling on a 50x50mm surface. I'm going to search which sensor (phototransistor, or led) does this best and how to process data to locate it. FUN TIMES (I'm actually looking forward to it :))

The aim later is to have a large horizontal surface, an led or led-phototransistor array, with points appearing in a cluster (leds) and a kid aiming a ping pong ball at it, with the array recording how accurate his throw was. (It's for kids who've suffered strokes, hand-eye coordination + fun + aim)

Hope it's not too much info. anyway, thanks for the support, it's awesome! :)
