USING AN LDR SENSOR WITH ARDUINO Introduction Hi Everyone, This is my 1st Arduino's tutorial video. In this video i am going to show you how to use a LDR or Light Dependent resistor to turn on and off ...

Dark sensor Light and dark detection using an LDR For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to ...

Working of LDR controlled LED using Arduino As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the ...

pinMode(buzzerPin, OUTPUT): Sets the buzzer pin as an output. Read Sensor Values potValue = analogRead(potPin): Reads the value from the potentiometer. tempValue = analogRead(thermistorPin): Reads the ...

Arduino BH1750 Ambient Light Sensor Circuit Diagram The circuit diagram to connect BH1750 Light sensor with Arduino is shown below. I2C communication pins SDA and SCL of BH1750 are connected to ...

The amount of light reaching the LDR from the LED decreases as the pipe is bent, and with a simple divider circuit a voltage can be read by an Arduino.
