3. OBJECTIVE
New Control Mechanisms.
Two Controls for a Car.
DUAL-AXIS ACCELEROMETER and LEDs (Light
Emitting Diodes) configured as photo-detectors.
4. 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.
5. 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
7. 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.
9. 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.
