Lesson 12 PHOTORESISTOR MODULE
Overview
In this experiment, we will learn how to use the photo-resistor module.
Photo-resistor is very common in our daily life. it is mainly used in intelligent switch so as to
bring convenience to our life. At the same time, in our daily life, we also use it in electronic
design. So in order to use it in a better, we provide the corresponding modules to help us to
use it more conveniently and efficiently.
Component Required:
(1) x Elego Uno R3
(1) x USB cable
(1) x Photoresistor module
(x) x F-M wires
Component Introduction
PHOTOCELL:
The photocell used is of a type called a light dependent resistor, sometimes called an LDR.
As the name suggests, these components act just like a resistor, except that the resistance
changes in response to how much light is falling on them.
This one has a resistance of about 50 kΩ in near darkness and 500 Ω in bright light. To
convert this varying value of resistance into something we can measure on an Arduino's
