Enter, save, and run 2BitRemoteBoeBot.bs2.
Make sure the power switch on the Board of Education is in position-2.
While pointing the remote at the Boe-Bot, press and hold the CH+ button, and
verify that the Boe-Bot rolls forward.
Repeat the test with the 1 key, it should have the same effect.
Test the CH+ , 1 , CH- , 2 , VOL+ , 3 , VOL- , and 4 keys.
Have fun driving the Boe-Bot around.
These programs are written for Boe-Bots with Parallax Continuous Rotation servos. If
your Boe-Bot is labeled with the letters "PM" highlighted in blue, you will need to use
different
servos, use 500 in place of 650 and 1000 in place of 850.
For some of the maneuvers, my Boe-Bot seems jittery, why is that? It has to do with the
way the program detects the start of the IR message. It doesn't always get detected on the
first try. We'll fix that in the next activity.
