Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...

We’ll be using this module to detect light or dark and monitor the output of LDR op-amp sensor module using Arduino Serial Monitor. Components required 1. Arduino UNO x1 2. LDR x1 3. Resistors 330Ω x2 ...

Connect the positive lead of the LED light strip to Arduino’s 5V pin, and the negative lead to the GND pin. If you’re using an RGB LED strip, there may be additional leads for red, green, and blue.

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 ...

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is ...

Connect an external 5VDC (1A) to VCC of 8×8 LED Matrix; Connect external 5VDC supply’s GND, to the GND of 8×8 LED Matrix Module; Note that the 8x8LED Matrix Module should be common-grounded with ...
