Power supply construction....

              Power supply is one of the main thing that must be have in electrical circuit. From the power supply, the component like sensor, PIC, LCD and many more get the source voltage to be turned on. Power supply can be battery, DC power supply, AC power supply, linear regulated power supply, switched-mode power supply, programmable power supply, uninterrupted power supply high voltage power supply, and voltage multiplier. For this project, the power supply that have been chosen is DC power supply with 5V output. This is because all the electronic device in this project using 5V input supply.

               Below is the step to built power supply with 5V output.

This is the simulation from Proteus software. From this diagram, decision about what component with necessary value can be made. After get the appropriate value. In this project the output that have been chosen is 5V.

The figure shows that component that will be used to build power supply. The resistor that has been chooses is 10k ohm. Whether the capacitor value is 10 mikro farad and the regulator serial number is 7805. The last number, 5, describe the output is 5V.

The figure shows power supply when have complete connection.

Figure shows that the power supply circuit connection was properly connected. The LED ( Light Emitting Diode) shows that the circuit function well.

Figure shows that output objective was nor required. From research, the regulator have tolerant between 

4.8 V to 5.2 V. So, the output that has been measured is still in regulator tolerant. The maximum input voltage is 35V to get 5V output. Below is the tables derived from research that have been done.
