Arduino Projects and Tutorials - Free Arduino Courses Online - Raspberry Pi & Arduino Serial Communication | The Complete Robotics Guide

This video provides a straightforward tutorial on establishing serial communication between a Raspberry Pi and an Arduino. We cover the essentials of UART connections and demonstrate Method 1 for transmitting data from an Arduino to a Raspberry Pi using USB. This setup is perfect for anyone working with a microcontroller and looking to enable device interaction.

That's because the Pi is busy running an operating system! The solution? Let the Raspberry Pi do the heavy thinking (like AI and vision), and send commands via USB to the Arduino to do the heavy lifting. 00:00 Introduction 00:18 What is Electronic Communication? 00:38 How Serial Communication Works (Bit Logic) 01:05 Understanding the UART Protocol 01:21 Role of TX (Transmitter) and RX (Receiver) Pins 01:42 UART Connection Logic & Cross-Wiring 02:16 Method 1: Arduino to Raspberry Pi Serial Communication via USB Cable 03:10 Explaining Baud Rate (Speed Synchronization) 04:45 How to Find the Arduino Device Name (/dev/tty*) 06:36 Demo: Successful Arduino to Pi Communication 06:55 Project: Sending Sensor Values to Raspberry Pi 08:25 Sending commands from Raspberry Pi to Arduino using Serial 10:18 Method 2: Physical TX and RX Pin Communication between Raspberry Pi to Arduino 10:40 Voltage Safety Warning: 5V vs 3.3V GPIO 12:30 Configuring the serial0 Interface In this video, I’ll show you the safest and easiest way to connect these two powerhouse boards together using Python (PySerial) and Arduino IDE. No complicated voltage dividers required—just a simple USB cable! @AtiumOfficial #altiumstories #raspberrypi #raspberrypiprojects
