Circuit Documentation

Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller board interfaced with a 16x2 LCD screen that uses an I2C communication protocol. The Arduino UNO provides power to the LCD screen and facilitates data communication via the I2C bus. The LCD screen is used to display text or data processed by the Arduino UNO.

Component List

Arduino UNO

  • Description: A microcontroller board based on the ATmega328P.
  • Purpose: Acts as the central processing unit of the circuit, controlling the LCD screen and executing the embedded code.
  • Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0-A5, SCL, SDA, AREF, D0-D13.

LCD screen 16x2 I2C

  • Description: A 16-character by 2-line display that communicates over the I2C bus.
  • Purpose: Displays information sent from the Arduino UNO.
  • Pins: SCL, SDA, VCC, GND.
