Circuit Documentation
Summary of the Circuit
This circuit integrates a Raspberry Pi Zero W with two sensors: the KY-033 Line Tracking Sensor and the Sensor FC-51 IR. The Raspberry Pi Zero W serves as the central processing unit, interfacing with the sensors to receive input signals. The KY-033 sensor is used for line tracking, typically in robotics applications for following a path. The Sensor FC-51 IR is an infrared sensor that can be used for obstacle detection or as a proximity switch.

Documented Code
No code has been provided for the microcontrollers in the circuit. To fully utilize the sensors and the Raspberry Pi Zero W, code should be written and deployed to the Raspberry Pi to initialize the GPIO pins, read sensor data, and perform the desired actions based on the sensor inputs. This code would typically be written in Python, using libraries such as RPi.GPIO or GPIO Zero to interface with the GPIO pins.
