Summary of the Circuit

This circuit integrates an Adafruit L3GD20H Triple-Axis Gyro Breakout Board with an Arduino UNO microcontroller. The purpose of this circuit is to allow the Arduino UNO to communicate with the gyro breakout board, likely for the purpose of measuring and processing angular rate data. The gyro breakout board is interfaced with the Arduino UNO via I2C communication protocol, utilizing the SCL and SDA lines. Additionally, the gyro is powered by the 5V supply from the Arduino and shares a common ground.
