PROJECT 2: LIGHT DIMMER
IN THIS PROJECT, YOU’LL CREATE A DIMMER SWITCH BY ADDING A POTENTIOMETER TO CONTROL THE BRIGHTNESS OF AN LED.
PARTS REQUIRED
• Arduino board
• Breadboard
• Jumper wires
• LED
• 50k-ohm potentiometer
• 470-ohm resistor
A potentiometer is a variable resistor with a knob that allows you to alter the resistance of the potentiometer as you turn it. It is commonly used in electrical devices such as volume controls on audio equipment. This project uses a 50k-ohm potentiometer.
HOW IT WORKS
The potentiometer manipulates a continuous ...
