COIN DISPENSING UNIT
The requirement of coins or change in a day to day transaction at places like bus stop, railway station, malls and parks is the main motive of designing this project. So we thought to develop an exchanger which will give us coins instead of notes. It is basically a coin dispensing model which accept note as input and checks it is real or fake. If the note is real, the camera takes a snap of it. After which it will find out its value using image processing technique and then accordingly the value equivalent to the number of coins are dispensed. For detecting kind of note the color histogram, color matching algorithm executes and the solution is given to the controller which will give command to the coin container through relays and motors, the user simply presses the keypad for which type of change he wants whether one rupee coins or two rupee coins or five rupee coins and hence in the output we get coins as per requirement.
