Circuit Documentation

Summary

This circuit is designed to control multiple DC motors using L298N motor drivers, with inputs from a rotary encoder, touch sensors, a joystick module, and an IR sensor. The STM32F407 Discovery Kit microcontroller serves as the central processing unit, interfacing with the input devices and controlling the motor drivers. The circuit is powered by a 12V 5A power supply, with voltage regulation provided by MT3608 modules. An AC supply is connected to the power supply to provide the necessary voltage conversion from AC to DC.

(Note: The code provided is a template and does not contain any functional code specific to the circuit's operation. It includes multiple inclusions of the same library, which is likely an error. The actual implementation code for controlling the motors and reading inputs from the sensors and the rotary encoder should be developed and added to the setup() and loop() functions.)
