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 detect ...

Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...

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 ...

The output of each LDR, I connected it to A1 and A2 pins of Arduino. Next step is to connect the servo motor, a servo motor has three wires, i.e. ground, V_in and a signal wire. I connected the V_in ...

The Light Dependent Resistor (LDR) is connected to the potentiometer of value 10k and the Analog to Digital conversion pin A1 of Arduino is connected to that point to note the voltage difference. We ...

The Arduino Uno records voltage variations across the LDR using Arduino’s internal analogue-to-digital converter (ADC) at a sampling rate of 25 (which can be changed by the programmer). It then takes ...
