hi i am new to pure data and am making a project where i need to make a patch where incoming digital data is converted in an analog out signal - PWM. if any one can help me that would be much apreciated. like i said i am a puredata new comer so as much detail as possble would be great.
many thanks

Hello,
What do you want to do exactly?
Controlling chips like PIC16C67 with your computer,
or making an emulation of PWM synthesis?

well the basic idea is that i will be using the output data of a gavanic skin response sensor to control the mood( colour of a room) though lighting.

i have looked around and found that ardurino board are good for this type of thing and found a piece of code that dims between 3 colours of LED.

I spoke to another person who said that using pure data i would need to amke a patch that convert the digital signal into an analogue one. Unofrtunatly he didnt elabourate on this and has left bit confused about how pure data links with teh ardurino boards?

if u can help into how i can achieve the result im after that would be great

cheers

The thing that will convert digital signal to analog is certainy not a pure data patch, it's an hardware process.

You can also control your hardware with a pure data patch and ARDUINO or HID externals.
