Title:


    LEDs as Sensors

Presenter(s):



Description:


    Imagine an LED that turns itself on and off in response to light levels, or one that you can blow out like a candle. These are circuits you can build with just an Arduino, a resistor, an LED and a little code. In this workshop, we will examine some surprising properties of LEDs to create systems that sense light, temperature and even wind speed.
