In this project you will create a dimmer switch by adding a potentiometer to control the brightness of an LED. You will learn how a potentiometer functions and interacts with the Arduino — effectively “translating” analog signals into digital and back.
Unlike general use single board computers like the Raspberry Pi, the Arduino – like other microcontrollers – lacks a simple human-machine interface. By programming your Arduino to respond to a potentiometer, you begin to harness the power of this microcontroller.
This is project 2 from the Arduino Project Handbook, V1 by Mark Geddes.
We built this project on a WorkBench Project Development Kit from Phase Dock.
