i am using Pd with arduino using the standard firmata and pduino to do the communication.
the patch i am using is devices message along with hradio object and open$1 mesage to open the serial port along with route digital to take in the inputs from the pir sensors
but i am getting to error messages

1. [import]: can't load library in 'flatspace'
2. unpack: type mismatch
   can someone help me in how do I overcome them
   thanks

Hi,

About no. 2, you are probably trying to unpack a different type of data than what [unpack] is set to. Have a look below:

If in doubt of which type of data is arriving to [unpack], then try exchanging it for a [print] and have a look at the console.

Hope this helps,
Gilberto
