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...
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, 1023, 0, 255); Then, using this value, the LED bulb is turned on and off. analogWrite(led, value); With this...
The Arduino Light Sensor Circuit The circuit we need to build is pretty basic, and you shouldn’t have too much trouble setting it up. I will briefly mention each of the parts that are in it and how to put it all together. The light sensor or also known as a photoresistor is the ...
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
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...

How to display LDR and soil-moisture sensor values using an OLED In Part I of this tutorial, we learned how to present data (or values) using a potentiometer (POT) and an organic light-emitting diode (OLED) display. For this project, the POT was an analog sensor (potentiometers can als...
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. ...
