the LED circuit connected to P14. These commands will have to be modified to control
the LED circuit connected to P15. Instead of using
HIGH 15
Example Program: TestSecondLed.bs2
' What's a Microcontroller - TestSecondLed.bs2
' Turn LED connected to P15 on and off.
' Repeat 1 time per second indefinitely.

Make sure the LED circuit connected to P15 is flashing. If the LED connected
to P15 flashes, move on to the next example (Controlling Both LEDs). If the
LED circuit connected to P15 is not flashing, check your circuit for wiring
errors and your program for typing errors and try again.
