This project is based on some great python xmas light code from the LightShowPi project, and advanced users can even. Using a RasPi, RGB LED Strip and some wire, make yourself a dynamic display and media player. You can follow this video tutorial in detail. A Spectrum Analyzer shows the loudness of different frequency bands (low, mid, high) in real-time, letting you visualize music. Therefore, this guide is very interesting. We will explore all the features like video streaming, image capturing, autofocus, auto exposure, auto gain, brightness control, special effects, white balance, EV control, saturation control, and all other features. We will use it with Arduino UNO Board, then with ESP8266, and also with ESP32 Wifi Module.

In this tutorial, we will go through the camera design, specifications, pinout, and the method to use it. Both of the cameras look similar though the difference is in pixel resolution and autofocus feature. They both have an SPI interface which means it requires only 4 wires apart from VCC & GND for communication. These are two different camera modules one with a 3megapixel feature and the other with a 5megapixel. It’s a very small camera module called Arducam Mega Camera.

When I opened it, I found 2 boxes which have the Camera module. A couple of weeks ago, I got this parcel from Arducam.
