Aim of the project:
The amount of money needed is given in the Serial monitor and the desired number of coins are dispensed out. The five rupee coins are stacked in a pipe,the two and one rupee coins are stacked in a similar way. The servo motors rotate and the required number of coins are dispensed out. for example, when the input is given as 38, seven 5 rupee coins,one 2 rupee coin and one 1 rupee coin is dispensed out.
List of components used:
- Arduino Uno R3
- Servo motors
- pipes
- cardboard
Day 1:
Initially the plan was to make a coin sorting and counting machine which could separate the different coins and count the number of five,two or one rupee coins. But we faced a difficulty. The radius of five and one rupee coin was almost similar. so we had to drop this idea.
Day 2:
Then we had to change the plan and we decided to make a coin dispenser. Basic idea of our project is that the input has to be given in the serial monitor and the desired number of coins are dispensed out. Day 2 marked the beginning of the hardware. My teammate, Teja Krishna Sai took the responsibility of hardware and arduino connections. Another teammate, Vishwas took care of the design of the project and me(Aditya Ashvin) took responsibility of writing the code.
Day 3
By the end of day 3 the code and the hardware was ready.

Final day:
our project worked the way we wanted it to work and it was appreciated by many. We won the first prize(EAC section) and were awarded with a Raspberry pi.
