Abstract
The CoinSaver 3000 counts the number of coins inputted into the shoots and displays the total value on a quad 7 segment LED display as shown in Figure 1, the maximum amount the LED can display is $99.99. The CoinSaver can also dispense the coins one at a time using servo motors attached to the bottom of the shoot. The servo motors are controlled by a 4x4 matrix keypad. When a designated key on the keypad is pressed, the corresponding servo will rotate 180 degrees pushing a single coin through a slit on the bottom of the shoot.
