Your Turn – Making Application Backup Copies
You will use and re-use the application programs you have developed in Activity #2
through Activity #4.
ACTIVITY #5: KEYPAD BOE-BOT DIRECTION AND DISTANCE
In this activity, you will program the Boe-Bot to receive direction and distance
information from the infrared remote. Here is how the program will work:
By writing a Boe-Bot main routine for IrRemoteKeypad.bs2, you can make use of its
button code and keypad entry subroutine features. This will make writing a main routine
that allows you to choose the direction with CH and VOL keys and then enter a number of
pulses with the keypad much easier to develop.

Create a separate folder for your application programs.
Make backup copies of IrRemoteButtons.bs2, 7BitRemoteBoeBot.bs2, and
IrRemoteKeypad.bs2.
Press/release a CH or VOL key to select one of four maneuvers: forward,
backward, rotate left, or rotate right.
Next, use the keypad to enter the number of pulses to deliver.
When the ENTER button is pressed/released, the Boe-Bot executes the maneuver.
Open IrRemoteKeypad.bs2 and save it as KeypadDirectionDistance.bs2.
