Arduino and Raspberry Pi?

[Willem]

Hello,

I am not sure if this is placed in the right section, but...

My Raspberry Pi arrives this Tuesday according to UPS and Farnell. I have been preparing stuff and I am curious if it is possible to make an Arduino (the Due for example) work together with the RPi.

An example: control a servo from a webpage, the webpage sends information to the RPi, the RPi sends information through the GPIO and then the Arduino recieves that information and executes an operation.

I might wait for an Assembled Gertboard but I'm not sure if that is as easy to program as an Arduino.

Regards,
Willem

While I do not have that particular application running I have several projects that I have built using both the Pi and a UNO. Should be very possible, but that may depend on your programming skills.

I was planning to make a robotic arm (using servo motors), and control it from a webpage

Not sure if I need some communication interface (I'm very new to these), or if I can just send signals but the options would be limited if I did that.

You can control servos attached to an Arduino from Python using pyFirmata. Works quite well, but the documentation is very minimal. Here's a small example I wrote, but it's mostly a Tkinter wrapper.

I use an Uno connected to the USB on the RPi. I send commands to the Uno to control a telescope using the Meade ASCII command set. The RPi is programmed in Python.

could you please post how to send ASCII characters via the UART using the GPIO or the USB, i have been programmed PICS with CCS so idont have any idea of how to do it in the raspberry , could any body tell my how to do it step by step, which program or interface use to do it

thank you
