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 ( 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 smiley)

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! smiley
