Circuit Documentation
Summary
The circuit in question is designed to interface an Arduino MKR WiFi 1010 with a variety of sensors and a rotary encoder. The sensors include a water level sensor, an MQ-2 gas sensor, a TEMT6000 ambient light sensor, a steam sensor, and a DHT11 temperature and humidity sensor. The rotary encoder provides user input. The Arduino MKR WiFi 1010 serves as the central processing unit, reading sensor data and responding to the rotary encoder's input. The circuit is powered by the 5V output from the Arduino, which is distributed to the sensors and the rotary encoder. Ground connections are also distributed from the Arduino to all components.

Documented Code
No code was provided for the microcontroller. The documentation of the code would typically include a description of the functionality, setup, and loop functions, as well as any functions or libraries used to interface with the sensors and the rotary encoder. Since no code is available, this section cannot be completed. If code becomes available, it should be documented here with comments explaining the purpose and functionality of each section of the code.
