Accelerometer and LED Sensor Array Based Remote Control Car
FINAL YEAR PROJECT
Project Guide : Prof. Ankita Patel
Project Co-guide : Prof. Kavita Joshi
Group Code : ETC15
Group Members : ANIKET BHOR
New Control Mechanisms.
Two Controls for a Car.
DUAL-AXIS ACCELEROMETER and LEDs (Light
Emitting Diodes) configured as photo-detectors.
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
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
on Tx Side
on Rx Side
FREESCALE MMA 7361L DUAL-AXIS
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
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.
