Complete Arduino Code and Demonstration Video is given at the end of this project. Here, we are defining the Pins for Relay, LED and LDR. #define relay 10 int LED = 9; int LDR = A0; Setting up the LED ...

This LDR Plus GSM Based Security System project will teach us how to make a smart device that can notify us whenever any unauthorised person opens the safe box/drawer. We all use safe boxes or drawers ...

Here three LDR sensors are used to control the brightness ... Learn here to interface RGB LED with Arduino. The complete circuit diagram of this project is given above. The +5V and ground connection ...

As a real turbidity sensor (which is sold in electronics stores) usually has a high price, the idea of this project came to replace such equipment with lower-priced ones and obtain a similar result.

In this project three variations in speeds are considered: stop, medium and high. Readings from the LDR are taken by analogue pin A0 using a voltage divider circuit consisting of 10k resistance and ...

Hi Everyone, This is my 1st Arduino's tutorial video ... In this very simple project, I am focusing on eliminating darkness. You can even use this as an emergency lighting system. The LDR is a special ...
