Week 12 - Week 13 (FYP II): Prototype Testing

Objective: To integrates all circuits into a prototype.


Analysis/Procedure:


There are four circuits placed in a box. The box is drilled and cut to display the LCD, to mount the push switches and for cables to connect with the power supply source. The box comes with four screws at the bottom to make sure the circuits are secure.


Four circuits inside the box are:

  1. PIC Circuit
  2. 80 KM/H LDR circuit
  3. 110 KM/H LDR circuit
  4. RS232 to TTL circuit







After numerous tests has been done, the objectives of this project has been achieved. The prototype successfully monitors and detects a speed exceeding the limit (as set using SMS). It successfully and effectively transmit and receive the data (alert) via SMS.




The prototype has been implemented using the circuitry knowledge of the author. Lastly, the system has successfully integrates a mechanical device (DC motor of the speedometer) and an electronic device (GSM modem).
