Try the Unmodified Code
Let’s try the ForwardLeftRightBackward.bs2 program from pages 107-108 in Robotics with the Boe-Bot v3.0 [1]. You might have noticed that the last serial command to the Arlo in the previous program was SEROUT 13, 32800, ["PULSE", CR]. That switched the Arlo’s DHB-10 from serial communication mode to pulse mode in preparation for this program. When the Arlo’s DHB-10 starts up, it automatically goes into pulse mode. So, another option for switching a program out of serial communication mode is to simply restart the DHB-10. You can do that by either pressing and releasing its reset button or turning Motors power off and back on.
The program would make a Boe-Bot turn about 90 degrees, but not so with the Arlo.
In the More Precise Maneuvers with Encoders section, we’ll get those 90° turns on the first try!
