Py-Arduino-Proxy is a Python library to communicate with Arduinos. BLOG del proyecto en español.

It's a low level tool, very easy to extend (it is very easy to create a new method in ArduinoProxy class and attach this method to a Arduino function). The project has many testing utilities and the ability to see DEBUG messages, to facilitate the location of problems and subsequent solutions.

A web interface is in progress. See the Web-Interface wiki page for instructions and screenshots.

Unresolved issues: currently, there are problems when working with interrupts, since characters may be lost if an interrupt occurs while reading the serial with Serial.read(). This is an inherent problem of serial communication of Arduino, but may be fixed in next versions of Py-Arduino-Proxy if a work-around is found.

See the install instructions on the wiki and the Videos section at the bottom of the page.

First connect to the Arduino.

Once connected, we can execute the methods on the instance of ArduinoProxy. For example, to read a digital pin:

To set output HIGH on a digital pin:

The basic methods of Arduino are implemented. The following actions can be done from Python:

• Check communication with Arduino (ping)
• pinMode()
• digitalRead()
• digitalWrite()
• analogRead()
• analogWrite()
• Get the value returned by millis() and micro()
• Run delay() and delayMicroseconds()
• watchInterrupt() and getInterruptMark() to work with interrupts
• shiftOut()
• Show messages on LCDs, based on the Hitachi HD44780 (or a compatible) chipset.

• Web interface + emulator + analog pins
• Web interface
• Testing shiftOut and 8 LEDs with Py-Arduino-Proxy
• Writing a custom method in Py-Arduino-Proxy
• Testing RGB leds with Py-Arduino-Proxy UI
