@ -7,19 +7,13 @@ Implementation of a Speed Limit Indication System Using a GPS Module
Objectives: Objectives:
1. The LED system on the microcontroller should indicate the vehicle's speed range using different colors for specific speed intervals. 1. The LED system on the microcontroller should indicate the vehicle's speed range using different colors for specific speed intervals.
2. The LED should remain off when the vehicle speed is equal to 0 km/hr. 2. The Green color LED should turn on when the vehicle speed is in between 0 km/hr and below 10 km/hr.
3. The Green LED should turn on when the vehicle speed is greater than 0 km/hr and below 15 km/hr. 3. The Cyan color LED should turn on when the vehicle speed is in between 10 km/hr and below 20 km/hr.
4. The Yellow LED should turn on when the vehicle speed is greater than or equal to 15 km/hr and below 30 km/hr. 4. The blue color LED should turn on when the vehicle speed is in between 20 km/hr and below 30 km/hr.
5. The Red LED should turn on when the vehicle speed is greater than or equal to 30 km/hr and below 40 km/hr. 5. The Yellow color LED should turn on when the vehicle speed is in between 30 km/hr and below 40 km/hr.
6. The Red LED should blink rapidly when the vehicle speed is greater than 40 km/hr. 6. The Red color LED should turn on when the vehicle speed is in between 40 km/hr and below 50 km/hr.
5. The White color LED should turn on when the vehicle speed is above 50 km/hr.
Tasks :
1. Initalize UART for receiving data - Completed
2. Add Read data function - Completed
3. LED indication configuration - Completed
4. Initialize buffer to store data - Pending
5. Add received data to the buffer - Pending
6. Use received data to meet objectives - Pending
