OBJECTIVE  New Control Mechanisms.  Two Controls for a Car.  DUAL-AXIS ACCELEROMETER and LEDs (Light Emitting Diodes) configured as photo-detectors.

INTRODUCTION  Two-axis Accelerometer used as a tilt sensor  Detects how far the chip was angled from its neutral, (Horizontal) Flat position.  A digital o/p for both the x & y-axes  Which corresponds to how far the accelerometer was tilted & in what direction.

 A custom LED array was also used to control the car.  LEDs - Traditionally used as light producing elements,  They also produce a voltage corresponding to how much light they receive – brighter environments produce a greater voltage across the LED.  An Infrared Distance Sensor – For Obstacle Avoidance

FREESCALE MMA 7361L DUAL-AXIS ACCELEROMETER  An Accelerometer measures the acceleration  Used to sense orientation, vibration and shock.  Present in portable electronic devices and video game controllers. The accelerometer (MMA7361 L) by Freescale Semiconductor.


4 BUTTON SENSOR ARRAY  4 LED SENSORS – Forward, Reverse, Left, Right.  To accomplish this, each LED was connected to an LM711 op- amp in a non-inverting configuration.
