Required Hardware for Connection

To begin, you will need a few key components:

* Arduino Board: Any standard Arduino board like the Arduino Uno, Mega, or even more advanced boards like the ESP32 can be used for this projectI'm using a Pixy2 Camera, so I cannot use the pins 10-13. I have toconnecttheSD CardAdapter (CS, SCK, MOSI, MISO, VCC, and GND) with the 

* SD Card Module: These modules are readily available and come in variations designed for either full-sized SD cards or MicroSD cards2024715—The communication between the microcontroller and theSD carduses SPI, which takes place on digital pins 11, 12, and 13 (on mostArduinoboards)  These modules typically include the necessary circuitry to interface the SD card with an Arduino's SPI pins2019316—I'll be showing you theconnectionsusing amicroSDmodule but they are pretty well identical for a full-sized SD module.
