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 ...

In our circuit we are going to use CA (Common Anode or Common Positive) type. In Common Anode type, if we want RED LED to be ON in, we need to ground the RED LED pin and power the common positive. The ...

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 ...

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 ...
