+===== Objective =====
+This lesson will show you how to program the mBot Neo to follow a line. It will then show you how test your program on the mBot Neo.
+===== Parts Required =====
+The parts below are required to complete this lesson. Note that all parts are included in the [[https://www.makeblock.com/pages/mbot-neo-coding-robot|mBot Neo kit]] that can be purchased on Amazon.

+===== Robot Testing =====
+Follow the steps below to test out the program you just created
+  - Place the line following map on the floor
+  - Place styrofoam blocks across the line to create obstacles
+  - Place the mBot on the line and slide the power switch on the mBot2 Shield on the mBot Neo to the ON position
+  - Press the B button on the CyberPi to start the mBot Neo moving
+  - When you're finished watching the mBot Neo follow the line, press the A button
+  - Change the distances in the else section to see how they change the mBot Neo obstacle avoidance
+<WRAP round help>Which values need to be the same?</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 42 through 44 above</WRAP>
