Summary

This circuit integrates a microcontroller, a Micro SD Card Module, multiple LEDs, a toggle switch, and a BNO055 sensor. The microcontroller used is an Arduino UNO R4 WiFi, which manages the communication with the Micro SD Card Module and the BNO055 sensor, as well as controlling the LEDs. The Micro SD Card Module is connected via SPI to the Arduino, and the BNO055 sensor is interfaced through I2C. The LEDs are individually controlled by digital pins on the Arduino and are turned on or off based on the logic level at these pins. The toggle switch is used to control the ground connection to the LEDs.

Component List

• Micro SD Card Module: A storage module that allows the microcontroller to read from and write to a micro SD card using SPI communication.
• LED: Two Pin (red): A basic red LED that emits light when a forward current passes through it.
• Toggle Switch SPST: A single-pole single-throw switch that can connect or disconnect the circuit it is part of.
• BNO055: A 9-axis absolute orientation sensor with I2C communication that provides acceleration, orientation, and magnetic field strength data.
• Arduino UNO R4 WiFi: A microcontroller board based on the ATmega328, with integrated WiFi capabilities. It is the central controller of the circuit.
