 Joystick:
 In order to operate the Joystick you will first need to access the Freenove Ultimate Starter Kit Tutorial. You can access this tutorial by searching in a browser "Freenove github". After searching this access the tutorial for the "Freenove Ultimate Starter Kit". After accessing this you will need to scroll down to chapter 12 which contains details on the analog digital converter and the Joystick. You can then follow the different steps to set up both the analog digital converter as well as the joystick. After you have finished setting them up with the one time operations you can then follow the diagrams of the tutorial to connect the converter and Joystick to your Raspberry Pi.
+Buzzers:
+Your Raspberry Pi/Pico starter kit should have two buzzers; one active buzzer and one passive buzzer. Both buzzers make use of electromagnetic induction to produce a sound, hence the name "buzzer." The difference is that the active buzzer has an oscillating source, meaning it will beep if Direct Current (DC) signals are used, while the passive buzzer does not. Instead, the passive buzzer can adjust its oscillation frequency to emit different pitches or notes. In other words, the active buzzer will activate when certain conditions are met and only turn off when the status quo is back to "normal," such as with alarms systems, while the passive buzzer can be used to make songs.
