In this page there is a content for the week 5 group assigment whichg covers the use the test equipment in the lab to observe the operation of a microcontroller circuit board

Multimeter tests
I tested the direct current and continuity using multimeter. The value of the DC from Regulated DC Power Supply is shown bellow.
Continuity shows the completeness of the circuit, which means the components are well connected. To test switch to the sound icon on multimeter, then test. If the there is a break in circuit there will be beeping sound.

Oscilloscope

An oscilloscope is an essential tool for analyzing electrical signals. It helps visualize voltage waveforms over time, making it useful for debugging circuits, measuring signal characteristics, and analyzing noise.

the Videos below represent the signal from the microcontroller to the LED. When there is a signal from the microcontroller, the waves on oscilloscope stops depending on the delay of the signal at each LED.
