+**Important Node**
+
+While we can leverage Python scripts to manage peripheral control at boot and shutdown, the ROSRiders driver offers a software-based approach to dynamically activate and deactivate peripherals in response to ROS node lifecycle events.

+**Understanding Hibernation** 
+
+The ROSRiders driver leverages the I2C bus to communicate with the ROSRider card. By powering the I2C port on the ROS2RPi, a wake-up signal is generated, awakening the ROSRider card from a low-power state. This allows for efficient power management and quick activation when needed.
