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...

You won’t need very much equipment with most of it being very basic parts that you would probably already have if you bought an electronics starter kit. This is very similar to the Raspberry Pi LDR sensor tutorial, but our circuit & code is a lot easier. This is because the Arduino ...
Now using an if condition, we will set a condition that if sensorValue is less than 500, the LED will turn on, and the serial monitor will print the line “The value of LDR is = sensorValue” with a delay of 1 ms. else{digitalWrite(ledPin,LOW);// This will set the pin 13 as ...
