A DC power supply is an electrical device that convert the AC current in to DC current supply using a rectifier circuit.
We supplied 0.01A and 5V to the PCB. Using the Formula P=IV, the power supplied to PCB is 0.5Watts.

We used the Oscilloscope to display the electric signals over time.
We use oscilloscope to observe the signal from Hello World Board. The programme loaded into board makes the led blinks.
After powering the Hello Board, we used oscilloscope probes to anode of LED and GND.
