Learn how a LDR light sensor module works, how to connect the LDR light sensor module to Arduino, how to program Arduino to detect the light. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help
Hello friends, Welcome to my SriTu Hobby blog. So far we have described 20 articles through the blog. Each of these articles explains the basics of Arduino components. You can read these previous articles. So let’s go to today’s post. Today we are going to talk about the LDR sensor....
First of all we have configured the A4 pin of the arduino uno as input pin to read the the LDR sensor output. In the setup function, the “Serial.begin(9600)” command will help in communication between the Arduino and serial monitor. In the loop function, we will read from the sensor...
In this project anArduino Nanois used, which works as a controlling unit. Two LDR’s (Light Dependent Resistor) are also connected to analog pins of the Arduino. A dummy solar plate is attached in parallel to the axis of servo motor and both the sensors are kept on the dummy solar plat...
Arduino LDR sensor interface code Following is the arduino code compiled and uploaded to the arduino board using Arduino IDE. #define LDRpin A0 // pin of the arduino board i.e. A0 where LDR sensor and resistor are connected int LDRValue = 0; // Variable where LDR sensor reading is store...
is higher, the analog value will be higher. We have set a threshold value in the code, which is 500. So, when the value is lower than 500, then the Arduino will turn on pin 13, where it has a built-inLEDthat will glow up. You can also connect a LED to any other pin you ...
5.Now we’re ready to turn it on and deploy the code. If you have had any trouble, please refer to the diagram below. The Code Much like the circuit, the code for this Arduino photoresistor tutorial is very easy to follow. Again this is just covering the basics of this cool electron...
