hello all

Im trying to make a money counter

I have the mechanics to sort out the different coins, but I want to know how many of each coin counted. I want to put a sensor on each output tube for the coins, so that when a coin passes, it will trigger the count up one.

so ( UK coins here ) I have 1p, 2p, 5p, 10p, 20p, 50p, £1, £2 coins

counting the 1p, 10p, & £1 will be easy, as they will onlt need to increase by 1
but the 2p, 20p & £2 will have to count up in 2s
and the 5p & 50p will count up in 5s

I know how to make the display, and how to get it to count up for one at a time, but can anyone help me in how to count up in 2s & 5s ?

thanks

Simon

One way -
Use one shot to trigger second one shot on tuppence tube, and use five cascaded one-shots for the - um - nickels? Do they call them nickles?

Another way -
Use multiple sensors in the relavant tubes. Tuppence would trigger two sensors. 50p piece would trigger five sensors.
