Introduction: COIN SPLITER AND COUNTER
Nowadays automation plays a major role in every field which reduces manpower and increases efficiency. This project deals with the separating of coins and currency and counting the total amount of coins. More number of Indian temples has donation boxes. Separation and calculation of currency and coins that are inserted into the donation boxes need more human intervention. Nowadays these processes completely depends on human hands. It requires more time and man power to separate and to calculate coins and currency. This project adapts automation for this time-taking process. Thus making the process more fast and accurate.
Step 1: VIBRATOR AND SEPARATOR
There is a fan attached at the top of the system so as to remove any currency notes and it will be collected at the box attached to the left corner of the system.
There is also a vibrator system attached at the bottom of the mesh arrangement to vibrate it and as a result the coins on the mesh falls one after the other in a sequential manner.
Step 2: IR COUNTER
The IR sensor is attached at the bottom (exit point) of the system.
It detects the flow of coins through the passage and hence increments the value of the respected coin's quantity.
Step 3: ARDUINO BOARD
THE ARDUINO BOARD IS THE HEART OF THE CIRCUIT, AS ALL THE NECESSARY
PROGRAMS ARE FED INTO THIS BOARD AND IT MAKES AN CONTROL OVER THE ALL,
The ATmega328 is a single chip micro-controller created by Atmel and belongs to the megaAVR series. The ATmega328P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega328P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Step 5: WORKING
In India, there are more number of temples which have a lot of donation boxes. Many people use them and insert coins and currency notes into that as their religious donation. Separation of coins and currency and counting them is a very time taking process which needs more manpower for that work. This is not reliable for today’s fast world. So we have to take corrective actions against that process. There are some machines available to count the currency notes but they not suitable for this purpose. Sorting of coins is a very time taking and bored job.
The methodology used in this model is an embedded system, an Arduino controller is used to control the whole system. It involves the system with a vibrating grill followed by the separating path. It involves the use of IR sensors as counters and has a LCD display as a displaying unit.
This system consists of a blower, vibrating motor fitted with grill, coins linear arrangement path, coins sorting path with collection boxes, counting unit and display. The system is fully enclosed by wooden walls. There is a small opening on the top of the system which is used to put the currency notes and coins into the system (donation box). At the time of insertion of currency and coins the blower starts blowing the currency into the collection box. To avoid the currency note reaching the coin separation path there is grill arrangement which is vibrated by a cam fitted with a motor. Due to this grill arrangement, only coins will reach the coin linearising path to make the movements of the coins linear for the sorting purpose. This unit is followed by the coins sorting unit which has projections or disturbances to sort the coins. These projections are equal to the diameter of the coins. On the sorting path itself sensors are mounted to count the coins. The denomination of coins are displayed on the LCD display.
