LDR Interfacing with Pic Microcontroller Light Intensity Measurement with Pic Microcontroller Automatic Street Light Control Dark Detection Circuit BH1750 Schematic As we mentioned earlier, BH1750 ambient light sensor can be interfaced with Arduino through I2C bus pins such as SDA and SCL that are A4...
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...
In the else section, the LED will turn Off using the digitalWrite function. The serial monitor will print the line “The value of LDR is = sensorValue” with a delay of 1 ms. Conclusion Here we have summarized the things we have learned in this article: ...
A method for modifying street light illumination by using sensor (LDR) which specialize in minimum electrical energy consumption. The sensors would detect the absence of natural light and will get automatically switched on and vice a versa. The brightness can be controlled through the Arduino. ...
