In my case, the USB serial port it is connected to corresponds to “cu.usbmodem1421”. Most likely if you are working on Windows you will find more ports listed.Īrduino IDE, port that Arduino UNO is connected to You will get an output like the following in the console. # REQUIRED LIBRARIES library(tidyverse) library(serial) library(magrittr) library(plotly) listPorts() To get a list of the serial interfaces available on your computer, you can simply use the listPorts() function. Starting a new script in R, you will load the previously mentioned libraries.

You can install them as follows: # PACKAGE INSTALL install.packages(c('tidyverse', 'serial', 'plotly', 'magrittr')) Working with the serial interface Plotly will allow you to create interactive web graphics from “ggplot2” graphics. Serial allows to read and write binary and ASCII data in RS232 / RS422 / RS485 or any other virtual serial interface of the computer. Tidyverse is a collection of R packages designed for data science tasks like data visualization and handle. Schematic interoperability project Arduino & Rįor the RStudio part, we will need the “Tidyverse”, “Magrittr”, “Plotly” and “Serial” packages.

When all is done, this is what you want to achieve using R and Arduino, working together:

Finally, you will read the angles of the motor and you will finish visualizing it with “ggplot” in Rstudio.

Once the Arduino detects that there is serial data again, it will read each value (0–255) on the serial interface, assign it to an angle rotation value (0 ° to 180 °), rotate the servo, and send the angle back to the serial interface.

Then, you will use these values (in a range from 0 to 255) to create a data set to turn a servo motor and pass these values to the serial interface.

Rstudio will read the values sent from Arduino to the serial port.

An Arduino script will wait until serial data is available, extract the brightness values for the 3 LEDs, assign them to analog values (0–255), instruct the onboard microcontroller to write these values to the LEDs, and then will send the mapped values (0–255) to the Rstudio-Arduino serial interface.

First, you will send a series of data defining the brightness of 3 LEDs (in a range of 0% - 100%) from RStudio to the Arduino serial port.

How is this possible? Using the Arduino’s ability to be programmed directly through a serial port.īefore we begin, here is an overview of what will happen to demonstrate interoperability between R and Arduino:

Arduino, on the other hand, will trigger peripherals based on the data it has received. In this context, R will handle the data and everything associated with it, and send it to the Arduino. This example is very simple, the objective of this article is to explore the interoperability between R and Arduino establishing a data flow between the two and having instructions in the microcontroller of the board, based on the received data. All that said, convergence can be achieved between the two: Data and IoT. Now, if you know R, you will know that an elegant language, well adapted to data analysis and data science. If this is your first time working with Arduino, I suggest you review this Getting Started to understand the minimum to continue with the examples in this article. Arduino software, on the other hand, is the board’s IDE where the set of instructions governing the board is written.

The Arduino microcontroller is responsible for keeping all of your compiled code and executing the commands you specify. You can tell this popular card what to do if you have the correct type of data and a set of instructions to process the data and perform subsequent operations.

What else could we talk about in common when we talk about R and Arduino, besides that they both share the letter R? Let’s start at the beginning, in case you are not familiar, Arduino is an open-source electronics platform based on easy to use hardware (Arduino board) and software (Arduino IDE).
