Arduino Interfacing with LDR sensor diagram and its working Following figure depicts arduino uno board interfacing with LDR at its 5V, GND and A0 pins. One can use other boards such as ESP32 or ESP8266 or any microcontroller boards for interfacing LDR sensor with analog read input. Arduino LDR...
Arduino - Light Sensor Arduino Uno's pin A0 to A5 can work as the analog input. The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023), called ADC value or analog value. By connecting a pin of the photoresistor to an analog input pi...
With this code, the amount of light in the bulb increases or decreases depending on the amount of light received by the sensor. Look at the code below. This code turns on the LED bulb when the sensor value reaches a certain value or higher. For that, the if condition is used. Please ...

The sketch is based on the LED blinking code from the previous recipe, but instead of using a fixed delay, the rate is determined by a light-sensitive sensor called a light dependent resistor or LDR (see Recipe 6.2). Wire the LDR as shown in Figure 1-8. Figure 1-8. Arduino with lig...
