Arduino connection problem

Hello
I have an arduino coonected to scratch, with catenary, followed the instructions,
catenury says is connected, and shows the com port of the arduino,
but when trying the blink,
it connects, and turns the light on the rx in the arduino (receiving)
so I know there is activity coming,
but the pin 13 doesnt light up
then I stop the program and the rx led stops,

so there is activity, is connected etc, why is the pin not lighting?

Thank you
wink

Re: Arduino connection problem

Does the basic arduino blink program work, without using firmata?

Re: Arduino connection problem

Also What version of firmata are you using?
Only 3.3.4 works

Re: Arduino connection problem

How to I use Catenary to read or view one of the Analog Input pins? I did
  broadcast pinMode 14 input (Analog input pin # 0).

But cannot figure out how to read the value.

Also, what are the 3 variables in the sample blink program "analogout" "pin" and "value" for?

Thanks!
