It’s like Dark and light Detector circuit but this time we are using Arduino to get more control over light. In this circuit, we are making a Light Sensor using LDR with Arduino ... All we have to do ...

First, connect ... from the LDR op-amp circuit and performs the decision-making accordingly. This method of interfacing an LDR with Arduino is simple, user-friendly, and typically preferred. For this ...

7. Fig. 6: PCB layout for motion sensor alarm Fig. 7: Components layout of the PCB Before assembling the circuit, do not forget to upload Motion_Detection.ino on the Arduino Nano board. After ...

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 another circuit or a LED. Wouldn’t it be ...
