Arduino Mega I2c, Documentation seems to say that I2C bus uses pins 20 and 21.
- Arduino Mega I2c, The I2C interface, also known as Inter-Integrated Circuit, is a widely used serial communication protocol that enables devices to exchange data over short distances. . The Arduino Mega features a dedicated I2C interface, allowing it to seamlessly communicate with other devices such as sensors, displays, and other microcontrollers. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. This Arduino Mega LCD I2C display project opens up incredible possibilities! Create real-time sensor data displays, user interface menus, status indicators, measurement readouts, scrolling messages, temperature/humidity monitors, countdown timers, and any application where visual feedback enhances user experience. Jul 8, 2026 · Arduino Mega 2560 pinout diagram and reference: all 54 digital pins, 16 analog inputs, PWM, UART, SPI, and I2C mapped, plus power rail specs and a pin table. Documentation seems to say that I2C bus uses pins 20 and 21. What Is I2C? The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Controller board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
