Trimpot Blink by aktechteacher

This sketch is missing a short description

In this circuit you’ll work with a potentiometer. A potentiometer is also known as a variable resistor. When powered with 5V, the middle pin outputs a voltage between 0V and 5V, depending on the position of the knob on the potentiometer. A potentiometer is a perfect demonstration of a variable voltage divider circuit. The voltage is divided proportionate to the resistance between the middle pin and the ground pin. In this circuit, you’ll learn how to use a potentiometer to control the brightness of an LED.
