This figure is the overall circuit of our system. The output of the accelerometer are passed into the input of the amplifier, and the output of which are passed into the ADC, which is PORTA of the STK 500, which is connected to the ADC input of the Mega32. The switches are connected to PORTC, and the TV output comes out from PORTD.

The amplifier circuit, accelerometer circuit and the TV circuits are described in the hardware section of this report.
