week 10

Title of the project: Run the project
Objective:
• To ensure the circuit is working properly when combined with hardware part
• To study about wiring / connection output circuit with AC load and AC power supply

Content/Procedure:
• Check the connection overall circuit with AC load and AC power supply
• Turn On the switch and run the project

Connection overall circuit with AC load and AC power supply
• In this part, correctly wiring is important. The DC voltage must connect to the PIC circuit, while 240 Volts AC supply connect to the valve and pump circuit.

Run the project

Analysis:
For the analysis in this task, the important note is how connection the output circuits with AC load and AC power supply. If wrong connection the circuit probably the component burn and if the projector touch the circuit, it feel some electric shock so to avoid this thing, exact connection must be applied.

week 9

Title : troubleshoot all the circuit
Procedure :
1) Multimeter
2) Supply
3) Wire
Analysis :
For the PIC circuit, it used 5 volt for the operation, for the supply I used 12 volt adaptor. When the supply 12 volt inject to the PIC circuit, it will automatically 5 volt supply to PIC. It is because it have voltage regulator on the circuit.

Picture 14 : voltage supply from adaptor

Picture 15 : LED show valve circuit is on

Picture 16 : Voltage signal from PIC

Based on picture above, it show the voltage when the PIC sending a signal to a valve circuit. For the valve and pump circuit it use directly plug in 240 volt.

Analysis :
As we know, PIC circuit is the most important thing to control this project. This circuit also use 5 volt to operated. From this circuit we can see the voltage regulator, so to operate the circuit, we must use adaptor 12 volt. Normally 12 volt and the voltage will stepdown by voltage regulator. For the valve circuit, it use 124 volt and high voltage. The safety is more important thing when to testing the circuit. From the troubleshooting the circuit, it has several problem can be detected:
1) When the circuit from input signal doesn’t have diode, it will burn the circuit when we got wrong on polarity connection. The diode will protect immediately the circuit. It wills shutdown the circuit automatically.
2) Shorting between the signal because of the soldering. Disconnect the soldering and soldering again.
Conclusion :
As the conclusion, in this part we know how to troubleshoot all the circuit and the objective is successful
