PyOnArduino

The purpose of PyOnArduino is to create a tool that can translate Python-like code to Arduino code. We pursue this target in order to program an educational robot that uses an Arduino microprocessor using Python.

Example

Example of PyOnArduino in action. On this example, the same Python + PyOnArduino code is compiled and uploaded to the robots and the behaviour is the same

Requirements and installation

  • Python 3.6 Download
  • Arduino IDE Download
  • Arduino Makefile Download and installation
    • Check makefiles folders and change the variables if the usb port or directories are different.
  • pySerial Documentation
  • To execute on mBot you need to add Makeblock libraries to the Arduino IDE following this repo
  • If you use MacOS and you want to execute on mBot, you'll probably new ch340 driver Download

To execute the project

    python3 translator/Translator.py [input-file] [robot]
    python3 translator/Translator.py [input-file] [robot] [architecture-file]

Robots supported

  • Complubot (Arduino Robot)
  • MBot
  • SergioRobot: This is an educational project not a real world development

Architecture file

A robot's architecture file can be added when executing PyOnArduino. On this file, added sensors' port can be added, so PyOnArduino can understand where to link them. Example:

    ultrasonicSensor = TK2
    rgbled = 7

To declare a sensor's port, just add the name + '=' + port name. Example files:

Complubot port names

  • ultrasonicSensor

mBot port names

  • leftMotor
  • rightMotor
  • ultrasonicSensor
  • rgbled
  • lightSensor
  • ledMtx
  • lineFollower

Problem with Complubot

There is a problem with Arduino Robot(Complubot). Sometimes when you upload a project it can make the usb port stop working. If you ever get to this point, the solution is quite simple. Write an empty sketch and upload it. While it's being uploaded press the reset button on the board two times. This should fix the problem! Source

Running Tests

To run the tests, run the following

python3 tests/<test-file>

To run specific tests for a bot, call the function in main and run the above command.

You can’t perform that action at this time.
