Title of Activity: Combine all the circuit development
Objective:
1) To complete the project
2) To see if all the circuitry can interact well with each other
3) To put all the circuit in a one place
Content / Procedure:
1) Take all the circuit and arrange it on a prospect, arrange it so all the circuit will look organized and simple.
2) Drill hole on the prospect to put screw so that the circuit does not move.
3) Connect all the circuit with the appropriate cable. From circuit to circuit we use cable to connect them but from main circuit to GSM we use RS 232 serial connector and for main circuit to computer we use USB to RS 232 serial cable.
4) After done placing the circuit and connect them, I make name tag for each of the component so that it will be easier to explain to the assessor.
Result and analysis:
1) I put the socket outlet at the top of the prospect for the power supply of main circuit and the GSM modem.
2) At the middle I put the main circuit so it easy to connect with another circuit.
3) At the bottom I put the GSM modem so that it antenna do not get caught with other thing.
4) Load driving circuit and current sensing circuit I put at the side of the prospect to make it easy to connect with the load that is electric motor that I put at separate prospect.
Conclusion:
1) All the work for combining the circuitry is finish and it is according to plan.
2) The circuit for motor starter control i have to do it separately because it take to much space.
3) The project is starting to come together.
