1. Description

The dimming lamp adjusts the brightness of LED via a potentiometer and an Arduino controller. The brightness is

subject to resistance value, which can be read and adjusted by connecting the ends of the potentiometer to digital or

analog pins on board. What’s more, this system is applied to control voltage or current of other devices such as fans,

bulbs and heaters.
