Week 26 (FYP 2): Use Adapter as a power supply

OBJECTIVE: 1. To use adapter as a power supply for this project.

          2. To have a suitable voltage that can make the project well function.

METHODOLOGY: 1. I buy adapter through online to make it as a power supply.

           2. Connect the adapter with the relay and the motor.

            3. Adjust the voltage of the adapter to 10 V.

RESULT:

Figure 24: Cable used for the adapter

ANALYSIS & DISCUSSION: Before this i used battery 9V as a power supply. But then when i met my supervisor, he advised me to use adapter as a power supply. So i decided to change the supply from a battery to the adapter. The adapter supply 12 V. I adjust the voltage of the adapter to 10 V. This is because when i use the bigger voltage, the motor moves so fast and it caused the water to come out fast. The sensor cannot detect well when the water come out too fast. That is why i adjust the voltage to 10 V.

CONCLUSION: Finally for the project, i used adapter as the power supply to replace the battery. The objectives have been achieved.
