2. Abstract
The Infrarat is an autonomous toy car that will use proximity sensors and a pivoting array of Infrared sensors for tracking a body and to avoid running into objects.
It will also wirelessly interface with an Android device to receive commands and send out a temperature gradient encoding. This stream of data will be transmitted from the IR array sensors to the device, where the data is rearranged and visualized.
It will be used in three modes which are follow, run away, and manual control.

4. Peripherals 5 I2C busses in master mode 3 PWM modules
Need 3 GPIO for bus expander
3 PWM modules
2 for the car motors
1 for the servo
Need 2 GPIO for motor controller
1 UART bus for Bluetooth in master mode
2 Timers for ultrasonic sensors in input capture mode
1 external interrupt for fuel gauge

5. Time Considerations Fast enough to decrease decision time
Mostly interrupt driven
I2C and UART are interrupt driven
Low latency between Android and car

6. Memory Considerations
64 KB RAM
Program and sensor data need to fit on RAM for fast processing
Limit flash access to prevent wasted cycles

7. Software Hierarchy

8. Status Android Application mostly done
Started code for initializations
To do
Data processing
Data fetching
Bluetooth interface
