Activity Controlling LED Brightness Using a Skills #Creativity
Potentiometer
Overview
In this activity, students will control the brightness of an LED using a potentiometer. By adjusting
the potentiometer, they will see how changing the resistance affects the LED’s brightness. This
hands-on activity helps students understand the relationship between resistance and light intensity
in an electronic circuit.
Learning Objective
Identify and describe the function of a potentiometer in a circuit.
Understand the relationship between resistance and LED brightness.
Gain hands-on experience in building and adjusting a simple electronic circuit.
Materials Required
Breadboard Voltage Regulator (7805) LED x 1 220 Ω Resistor x 1
