Description
Ready to connect the world of microcontrollers and microcomputers?
In this focused course, you’ll learn to bridge two of the most powerful platforms in modern electronics—Arduino and Raspberry Pi—using I2C communication. Whether you want the low-level control of Arduino with the processing power of Raspberry Pi, or simply need them to exchange data, this course shows you exactly how to make them talk.
You’ll set up both devices, assign master/slave roles, exchange sensor data, trigger actions, and build practical, responsive two-way systems.
Why I2C + Arduino + Raspberry Pi?
Efficient, two-wire communication
Works across different architectures (microcontroller + microcomputer)
Enables hybrid systems: sensor data on Arduino, processing on Raspberry Pi
Essential for building modular, scalable IoT and robotics platforms
What You Will Learn
How the I2C protocol works: addressing, clocking, and data flow
Configuring Raspberry Pi as I2C master or slave
Setting up Arduino for I2C communication using Wire library
Sending data from Arduino to Raspberry Pi and vice versa
Debugging communication and signal issues
Real-world project: Arduino reads sensor data → Raspberry Pi logs it or visualizes it
Best practices for voltage compatibility and device addressing
What You’ll Build
A sensor hub: Arduino collects data, Raspberry Pi logs and processes it
A control system: Raspberry Pi commands, Arduino executes (motors, relays)
A responsive two-device project that combines low-level control and high-level logic
Who This Course Is For
Arduino and Raspberry Pi users ready to integrate both systems
Makers, students, and engineers building multi-device projects
Hobbyists working on robotics, automation, or IoT platforms
Anyone needing real-time data flow between microcontrollers and computers
Requirements
Basic knowledge of Arduino and Raspberry Pi setup
Arduino Uno or Nano, Raspberry Pi (any version with GPIO)
Jumper wires, sensors or LEDs (optional for testing)
Python installed on Raspberry Pi, Arduino IDE on PC
Make Your Devices Talk
Your projects shouldn't be limited by a single board. Combine the strengths of both Arduino and Raspberry Pi with I2C—and build smarter, more capable systems.
Whether it's remote sensors, robotics, or smart home tech, this course gives you the skills to scale.
