+===== Robot Testing =====
+Follow the steps below to test out the program you just created
+  - Place some of the styrofoam blocks on the floor
+  - Place the mBot on the floor and slide the power switch on the mBot2 Shield on the mBot Neo to the ON position
+  - Make a loud sound (clap) to start the mBot Neo moving
+  - When you're finished watching the mBot Neo avoid obstacles, press the A button
+<WRAP round help>What should change in your program to make the mBot Neo respond to quieter sounds? Make that change and see if it works</WRAP>
+<WRAP round tip>When you're ready to try out changes to your program, connect the USB cable to the CyberPi on the mBot Neo, plug the cable into your computer, and repeat steps 31 through 33 above</WRAP>
