Week 2 FYP II

Title of activity:

PIC: explaining the schematic diagram (PART A, Voltage supply)

Objectives:

To introduce the function of every single component of PART A in schematic diagram.

Content/Procedure: 

The component consists in Part A is;

1. connector/adapter

2. diode

3. switch

4. voltage regulator

5. capacitor

6. electrolytic capacitor

7. LED

Connector/Adapter

is the connector to accept voltage from power supply which is 12V.

diode

- is used to change from alternate current into direct current.

- also to avoid voltage connected reversely.

switch

as the on / off button.

voltage regulator

- act as step down transformer

- to reduce the voltage received earlier from 12V to 5V

- to protect PIC and other components from over voltage

capacitor

are used in filter circuits.

electrolytic capacitor

- it conduct alternating current (AC) and block direct current (DC).

- to couple circuit blocks allowing AC signals to be transferred while blocking DC power

- to store energy

- to filter signals according to their frequency

led

as the proof that the circuit is functioned when it is turned on.

Conclusion:

Hence, now we know how the power supply was converted from 12V to 5V. This is a must because the components used cannot withstand over voltage. it may break down or burst.
