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...
The wiring schematic is very simple. We have connected the GND pin of the KY-018 LDR Module to the GND pin of our Arduino Board. Then we connected the middle pin to 5V, and at last we connected the S pin to pin A0 of our Arduino Board. These connections can be seen in the schema...
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 ...
Arduino Interfacing with Gyro sensor diagram and its working As shown in the figure-1, five pins of gyro sensor are interfaced with arduino board. The table below mentions connections between them. Arduino Gyro sensor interface code Following is the arduino code compiled and uploaded to the ardui...
LDR decreases with the increase of intensity of light and similarly resistors of LDR increases with decrease of intensity of light. let’s see how we can use light dependent resistor to measure intensity of light. We have connected one terminal of LDR with ground and other terminal of LDR is...
