Interfacing MSP430 PIR sensor board with Ardiuno Micro

I am trying to interface MSP430 PIR sensor with Ardiuno Micro using SPI interface. However Ardiuno is not able to read the sensor data. It reads only when I have connected flying leads between Sensor and Ardiuno.

Somebody, help in resolving the issue.

Only if you post your code to both sides of this and post a schematic of how it is wired up. Read the how to use this forum sticky post, it tells you how to ask questions.
