resistance of the sensor changes with intensity of the light and consecutively output voltage also changes. The arduino board can be used along with LDR sensor in order to read the analog voltage. By programming threshold value in the code and reading the realtime values of the voltage from LD...
After that, the sensor value is read and put into the integer variable. The variable name is called “value”. int value = analogRead(sensor); This code converts the value from 0 – 1024 to 0 – 255. This is because the PWM value ranges from 0 – 255. value = map(value, 0, 102...
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
Here is a simpleArduino projectthat focuses onadjusting the brightness of an LCDscreen whenever there isn’t sufficient light in a room. The Arduino reads the surrounding light intensity usingan LDR sensor. Theroom temperature and humidityrange will also be displayed on the LCD. The entire hardwa...
In this Arduino light sensor tutorial, I will go through the basics of setting up a photoresistor, so can detect changes in light easily.

In this section, we have assigned the sensor input pin as A0 and the led pin to 13 to turn the LED On or Off using Arduino. The sensorValue is initially set to 0. void setup ( ) { // code written in it will only run once. ...
I have built an Automatic Green House Controlling and Monitoring System over GSM module using Arduino. This system is very efficient for growing good quality plants. The other important part of this project is that it is fully automatic. Arduino automatically turns on and turn offs the appliances...
