59. Multi-Slave I2C Communication

Set up I2C communication between a microcontroller (Master) and three I2C slave devices.

I2C Slave Devices:

• RTC module (e.g., DS1307) for real-time date and time.
• BMP180 sensor for environmental data (temperature, pressure, altitude).
• OLED display (SSD1306) to display data.

Tasks:

• Read the date and time from the RTC module.
• Read pressure, temperature, and altitude from the BMP180 sensor.
• Display the date, time, pressure, temperature, and altitude on the OLED screen.
• Update all the readings every second.
