FYP Sem II : Week 5

Title of Activity:

Testing the circuit using breadboard

Analysis:

In order to ensure that the components that I bought are functioning or not, I do the testing on the breadboard. Basically, I test the circuit of power supply. In this project, I need 5V and 12V as the power supply of certain device and components. 12V can be obtain from the 12V adapter while 5V is obtain by constructing the voltage regulator module.

This the voltage regulator module circuit that I assembled on the breadboard.

 

By using 9V battery, I test it and measure the output value at output leg of LM7805 by using multimeter. The value of output voltage is nearly 5V which is 4.8V. Hence, it can be used to operate most of components such as microcontroller, LED and so on.

Other than that, I do the basic testing for each of the LED to ensure whether it is functioning or not. It will be on when it was connected to the circuit that I've been constructing before.

Conclusion:

All the tested component is functioning well and the output produces are same as the theory.
