Arduberry Grove Base Shield LED IO Error


I’m totally new to sensors and Arduino world. Here is my hardware setup.

Raspberry Pi B with Arduberry with Grove base shield with LED sensor.

I’m trying to run to blink my LED connected with digital port 4 and having problem. However, if I used sketch program then it works just fine.

Any ideas where I might be doing things wrong?
