In this Raspberry Pi course, we will learn about Interfacing Light Dependent Resistor with Raspberry Pi.
A Light Dependent Resistor (LDR) is a sensor that can detect the amount of light in its surroundings. This tutorial will show you how to interface an LDR with the Raspberry Pi and use it as a light detector.
The Light Dependent Resistor is a sensor that changes its resistance when it is exposed to different levels of light. It can be interfaced with the Raspberry Pi by connecting it in series with the GPIO pins.
The LDR is a voltage divider, which means that when the light intensity increases, the voltage at the output decreases. The LDR has two leads and one lead must be connected to ground for it to produce a stable reading.
This Raspberry Pi tutorial will show you how to interface a Light Dependent Resistor with your Raspberry Pi and use Python to get readings from the sensor.
1) Connecting the LDR
2) Setting up a Python script
3) Reading and Plotting Data
4) Troubleshooting Tips
There are many advantages of using an Interfacing Light Dependent Resistor with a Raspberry Pi. The first advantage is that it is cheap. The second advantage is that the resistor can detect different light levels, which means that it can detect the level of ambient light in the room.
The third advantage of using an Interfacing Light Dependent Resistor with a Raspberry Pi is that it has a long life span. The fourth advantage is that it has a wide range of sensitivity, which means that you can use it in any environment.
