A Simple Boe-Bot Main Routine
In the previous activity, you replaced the main routine in IrRemoteButtons.bs2 with a
code block that contained a

4BitRemoteBoeBot.bs2 from Chapter 1, Activity #5. The difference is, this time, it will
be really easy to write, and even easier to adjust and expand.
All you have to do with the next example program is open IrRemoteButtons.bs2, save it
under a new name, and modify the main routine. The IR remote code reading is taken
care of in a subroutine, so you can focus on programming the Boe-Bot, and all you need
to know is the value of the
subroutine.
Example Program – 7BitRemoteBoeBot.bs2
This example gives you all the number key features of 4BitRemoteBoeBot.bs2 from
Chapter 1, Activity #5, plus the CH+/- and VOL+/- key features from Chapter 1, Activity
#4.
