Hi
I am interesting how does the coin machine of the vending machine is working.
How does the machine make the difference between 5p, 10p, 20p and 50p :cry:
 

Re: vending machines

There are different options:

- meassure weight of the coins (electrical / mechanical)
- 'filter' it mechanically (at size) and meassure amount of different coins
- meassure inductance (different coins have different inductance)
