Upload “StandardFirmata” to Arduino
StandardFirmata is a code that helps Python get access to the Arduino board.
First, connect your Arduino to the computer/raspberry pi/laptop using the USB cable.
Know the port name the Arduino is connected to. In windows, the port name will be something like “COMx” (where x is an integer), while in Linux it will be a string starting with “/dev/tty”. You might find this information by opening Device Manager in Windows.
If you are using Linux, please refer to the official Arduino Documentation.
Next, you can open the Arduino IDE and follow the steps to upload the StandardFirmata to the board.
Get StandardFirmata: File -> Examples -> Firmata -> Standard Firmata
Specify Correct Board and Port: Tools -> Board -> Select Arduino UNO (or your own board) -> Tools -> Port -> Select your Port
Upload the StandardFirmata: Click on the upload button to upload the code to Arduino.
Control Arduino with Python and pyFirmata
In this article, we will learn how to link an Arduino to a Python script in order to operate the Arduino. This example of constructing a 4-bit binary up-counter using Python script to control Arduino helps us understand this better.
