Problem with python 3.2:

arduino.write(‘Y’) don’t work, i find people use raw_input() for this problem but python 3.2 don’t have raw_input.

Erro :
File “/usr/lib/python3.2/site-packages/serial/serialposix.py”, line 467, in write
t = len(data)

Do you know how?

I am new to interfacing Arduino to Python. I tried the example you have provided on this site.
When i run the code the output on the Python IDLE window is as follows :
“
Trying… COM4
Failed to connect to COM4
Failed to send!!
“
I am using Win7. According to the Arduino program the board is connected to the COM4 (that is also suggested by the device manager).
What can i do in this case ?

There was an other question i had in mind:
How does the python code identify what arduino code has to be uploaded and run. Or does it run the code that was previously uploaded?

Thank you in advance,
Cheers

I am having problems. I have used your code for both Arduino and Python. When I use the Arudino Serial monitor to send a ‘Y’ The LED comes on. When python sends it, the LED comes on for a second and then goes off again.

I have changed to pin 8 to ensure that it was not just flashing when it received data. But Pin 8 still works with the Serial Monitor, but again flashes on and off when I use Python.

I have altered the code on Arduino to make the LED flash a number of times when it recievies the ‘Y’ and this happens, so I know the all code is working to the point where the LED just turns off.

I am using Windows Vista 64 Bit if that makes any difference.

[...] The code for all this stuff is on Github. You’ll need to load up your Arduino with the serial.c file, which contains a simple serial protocol that brings a pin high on receiving a ‘Y‘ and low on receiving a ‘N‘. More information on talking to Arduinos with Python is here. [...]

Fantabulous tutorial. Its funny how rare it is to read a tutorial that’s not obfuscated by overly complicated details. This is just super clear and demonstrates everything needed to get the job done. Why aren’t more tutorials on the intershnitzel like this?

Arduino programming is interesting, even if the scope for Python programming is restricted to the host computer. One related project I found recently is this Python-based IDE:

http://code.google.com/p/arduino-pyqt/

Of course, the language is still the Arduino variant of C++, but it’s interesting to see work being done on tools for the Arduino.
