Lidar Lite sensor

Hello, 

Has anyone ever used lidar lite sensor with Firefly ? I couldnt make it work with Firefly. My unoread doesnt give me correct data.

I tried to hook up a light sensor, and it reads the data properly, so I assume that the wiring method may be wrong.

I can get the distance data from loading the arduino code as the attached image without using firefly and my wiring method is also attached in the images below.

I tried to change the connection of the digital pin 2 and 3 to analogue pin 0 and 1 to read the input from Firefly. However, it doesnt seem to be working . Does anyone have any idea?

I wonder if what will be the correct way to wire up the sensor to get correct data?  

Any help will be appreciated. Thank you very much!
