It’s like Dark and light Detector circuit but this time ... the light turns OFF. Complete Arduino Code and Demonstration Video is given at the end of this project. Here, we are defining the Pins for ...

In this flashing led lights circuit, the LDR or photoresistor is connected in such way that when the light intensity varies it will influence the flashing frequency and the brightness of the LEDs. T1, ...

That will further changes the intensity of red, green and blue color in RGB LED, and different colors will be produced. Below table shows the color combinations with respective change in duty cycles.

Looking for a simple circuit ... different color LEDs (Red, Green and Blue) are used. You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Here, 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 ... circuit. The LED will turn on when its dark and will go off when its bright. To achieve ...

connect LM358 ‘s pin 7 of to one of Arduino’s digital I/O pins. As a dark sensor, the circuit will output as HIGH when it’s dark and a LOW when there’s light. The output from the LDR op-amp circuit ...
