In this tutorial I’ll show you how to communicate between a Raspberry Pi and an Arduino board via Serial communication. First, I’ll quickly explain what is Serial communication. Then you’ll see how to setup your hardware and software, and we’ll dive into the Python code (Cpp for Arduino).

In this I show an alternative way to communicate between a Raspberry Pi and an Arduino by using the SPI (Serial Peripheral Interface) protocol. What is SPI? SPI is a serial protocol, which means that data is sent one bit at a time down a wire.

In this tutorial I’ll show you how to communicate between a Raspberry Pi 4 (also works with 3, 3B, 3B+) and an Arduino (Uno), using the SPI protocol. The Raspberry Pi will be configured as a master, and the Arduino as a slave. On Raspberry Pi we’ll use the WiringPi library inside a …

Feb 3, 2025 · Learn how to set up SPI communication between Arduino and Raspberry Pi with step-by-step guides, sample code, and troubleshooting tips for your projects.

This tutorial presents a basic framework for Raspberry Pi to Arduino communication and control using SPI - the Serial Peripheral Interface bus. SPI represents a very well established chip-to-chip communication methodology that is implemented in hardware on both devices.

Jan 29, 2025 · Learn how to establish communication between an Arduino and a Raspberry Pi using Serial (UART), I2C, or SPI. This step-by-step guide covers wiring, Python and Arduino code, and troubleshooting for seamless data exchange in IoT and automation projects.

Dec 29, 2024 · Connect your Raspberry Pi and Arduino using USB, allowing serial communication between the boards. Set up your Raspberry Pi as the master device to send commands, and configure the Arduino as the slave to execute those instructions.

Apr 5, 2025 · I want send data to/from Arduino Leonardo over SPI using wiringPi/pi4j on Raspberry, using custom GPIO as CS. Raspberry is supposed to be the master, and Arduino slave. Pi and Arduino are wired through digital levels converter - 3,3V to PI and 5V to Arduino.

Sep 4, 2021 · I'm working on a project - just for learning - where I'm trying to send joystick position - analog data - from Arduino UNO to Raspberry Pi 3B+ (WiringPi Library) using SPI protocol. So far, I'm able to send one byte from the master RPi which initiates the ISR on the arduino UNO.

Jul 4, 2017 · You want to connect an Arduino board to a raspberry pi board. There are several different ways to do it. It can be done with I2C communication, SPI or even the GPIO port on the Raspberry pi. But in this tutorial, we'll use a serial comunication.
