Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes multiple rotary encoders, push buttons, an infrared proximity sensor, an LED, and a Raspberry Pi. The circuit is designed to interface with the Raspberry Pi's GPIO pins for various input and output operations.

Component List

  1. Rotary Encoder

    • Pins: EncoderPinA (output pin A), EncoderPinC (common), EncoderPinB (output pin B)
    • Description: A rotary encoder is used to convert the angular position or motion of a shaft or axle to an analog or digital code.

  2. Push Button Round

    • Pins: leg0, leg1
    • Description: A push button is a simple switch mechanism for controlling some aspect of a machine or a process.

  3. Pi pinout

    • Pins: 3.3V, GPIO4, GND, GPIO17, GPIO27, GPIO22, GPIO25, GPIO24, GPIO23, GPIO18, 5V, GPIO2, GPIO3, GPIO14, GPIO8, GPIO15
    • Description: The GPIO (General Purpose Input/Output) pins on the Raspberry Pi are used to interface with various components.

  4. Infrared Proximity Sensor

    • Pins: Vout, GND, Vcc
    • Description: An infrared proximity sensor is used to detect the presence of an object or its distance from the sensor.

  5. LED: Two Pin (red)

    • Pins: cathode, anode
    • Description: A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it.

  6. Comment

    • Description: Used for adding comments or notes in the circuit design.
