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 ...

Learn here to interface RGB LED with Arduino. Circuit Diagram: The complete circuit diagram of this project is given above. The +5V and ground connection shown in the circuit diagram can be obtained ...

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.

A simple LDR controlled LED that cycles the LED power using a simple time based step function. It also uses simple charlieplexing to alternately light two leds using 2 wires, and that's because I use ...

In this circuit we are not using any of this complicated components. Instead of these, we are using two LDRs and one LED. LM1801 special-purpose IC ,which is designed especially for smoke detectors, ...

Circuit and working of interfacing of KY-008 laser LED module with Arduino Circuit diagram for interfacing of KY-008 laser LED module with Arduino is shown in Fig. 2.
