elements (Red, Green, Blue). Each color is controlled
separately by applying a positive voltage to its
respective anode (+).

Common Anode RGB LED: In this type, the RGB
LED shares a common anode (+) for all three-color
elements. Each color is controlled separately by
grounding its respective cathode (-).

Switch

A switch is like a bridge in a circuit that can be opened or closed.

When the switch is turned ON, it connects the circuit, allowing electricity to
flow.

When the switch is turned OFF, it breaks the circuit, stopping the flow of
electricity.
This opening and closing action of the switch controls the flow of electricity in a Switch
circuit, turning devices ON or OFF.

Multimeter

A multimeter is used to measure various properties like voltage,
current, and resistance.

It has probes that you connect to different parts of a circuit to take
measurements.

By selecting the appropriate setting on the multimeter, you can
measure voltage by connecting the probes across a component, current
by placing the multimeter in series with the circuit, and resistance by Multimeter
connecting the probes to the ends of a resistor or component.
The multimeter displays the measured value on a screen, making it easy to troubleshoot circuits
and diagnose problems.
