This page will help you get started with Marty's distance sensor add on using the python library. Before we get started, make sure you have [[:martyv2:userguides:python:start|python installed]] and [[:martyv2:userguides:sensorsandaddons:distancesensor|have set up your distance sensor]]. 

===== Step 1 =====


Import martypy and establish connection to your Marty. Follow the code below to connect your Marty.
<code python>
import martypy
# USB connection
# change "COM1" on this next line to specify the USB port you want to use
# comment this line out to use WiFi
my_marty = martypy.Marty("USB")

# WiFi connection
# uncomment this and change the IP address to your Marty's to use WiFi
# my_marty = martypy.Marty("wifi", "192.168.0.5")</code>

You should now be able to play with your distance sensor using the function below.

=====Let's Code!=====
The function //**get_distance_sensor()**// returns an integer of the distance of the closest object (in mm). 
Try this function using the code below:

<code>
my_marty.get_distance_sensor()
</code>
