Hardware Requirements Specification

HRS 01 – Microcontroller

• Finished
  • The project is based on the ATmega328PB, which provides overall system control.

HRS 02 – Motor

• Finished
  • The system includes specifications for motor power requirements, speed control. Specifically, the system uses 4 regular TT motors with a motor driver from Adafruit.

HRS 03 – Display

• Finished
  • The LCD is a 320x480 pixel display to show both system and alarm times, with user-friendly labels for setting modes. It communicates with the ATmega328PB through a 5-pin SPI interface.

HRS 04 - Speaker

• Finished
  • The speaker generates a sound within the range of 70-90dB to wake up the user.
  See the demo video for supporting evidence.

HRS 05 - Distance Sensor

• Finished
  • A distance sensor is used to detect obstacles.
  • If the distance sensor detects that the obstacle in front is less than 30 cm away, the ATmega328PB shall command the motor driver, controlling the device to turn right 90 degrees.
  See the demo video for supporting evidence.
