We'll display the analog value on the serial monitor. The photoresistor is made of cadmium sulphide tape, a semiconductor. In this case, looking through the photoresistor, the electrons in the middle see a small resistor and then 0V (ground) beyond that. Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. Use the Serial Monitor from the Arduino IDE to see the analog value. Ongoing donations help keep the site running. Arduino UNO x1 2. TranslateAnalogR=analogRead(RlightPin); //Read the right photoresistor value analogRead() is a slow function, and it is quite inefficient to do the analog to digital conversion twice. Project 01: Monitor how much light is hitting a photoresistor Components needed: Arduino Uno … The typical reistor is 10kOhms but you can also find the LDRs (like the one shown in the figure below) that already contains the resistor, in which case you don't need to connect the resistor. Serial.println(analogRead(RlightPin)); //Write the value of the right photoresistor to the serial monitor. In the " void setup " we initialize the serial monitor : Then, we read the analog value coming from photoresistor and we define it as " value " : And we write the value on the serial monitor : Second pin --> A0 ( a resistance is connected to the GND and to the photoresistor second pin ). Also see the Arduino Analog Input tutorial on the Arduino website that uses this sketch with a potentiometer and the above circuit from this tutorial. Arduino analog input A0 is used in the sketches below, but can be changed. Program for Arduino. How this works is the RGB LED lights each color in rapid succession while recording the value of the photoresistor for each color. pinMode(8, OUTPUT); // pin 8 as output } void loop() { PrValue = analogRead(Pr); Serial.println(PrValue); //prints photoresistor value . The LED is switched off when the analog value from the sensor goes above the threshold value. Photo Resistor Module Connections to Arduino: Geekcreit Photo Resistor Sensor Module Arduino Circuit.
