Hello friends, Welcome to my SriTu Hobby blog. So far we have described 20 articles through the blog. Each of these articles explains the basics of Arduino components. You can read these previous articles. So let’s go to today’s post. Today we are going to talk about the LDR sensor....
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...

Connection with Arduino Uno To interface, this light sensor with Arduino, we use I2C pins of Arduino Uno. The figure shows the connections of the breakout board with Arduino. Make connections with BH1750 with Arduino according to this table: ...
2.4: LDR Connection with Arduino explained with Voltage Divider. As R2=1K/4.7k constant, Vout will decrease if R1 decreases which is when light intensity is low and Vout increase when R1 is high which is when light is higher. Therefore the logic in Arduino should follow the principle that ...
This is very similar to the RaspberryPi LDR sensor tutorial, but our circuit & code is a lot easier. This is because the Arduino has analog pins making it super easy to read the value from something such as an analog sensor. You Might Also Like ...
The following sketch reads the light level of an LDR connected to analog pin 0. The light level striking the LDR will change the blink rate of the internal LED connected to pin 13: const int ledPin = 13; // LED connected to digital pin 13 const int sensorPin = 0; // connect sensor...
4. After setting up the module, let’s start with the sensors. You also need to learn the name of each pin for proper connection forLM35. Fig. 11:Pin Diagram of LM-35 Temperature Sensor 5. Connect the signal pin of LM35 to A0 of Arduino. For LDR(light-dependent resistor), you don...
