Circuit Documentation
Summary
This circuit integrates various components with an Arduino Uno R3 to create a system capable of receiving analog inputs from a thumbstick, processing infrared proximity sensor data, controlling multiple servos, and interfacing with a voice recognition module and an I2C LCD screen. The Arduino Uno R3 serves as the central processing unit, reading inputs and driving outputs based on programmed logic. The servos are controlled via PWM signals, and the thumbstick provides analog input for additional control or feedback. The voice recognition module allows for audio-based input, while the infrared sensor adds proximity sensing capabilities. The I2C LCD screen displays information or status messages.
