#2, but connect the circuit to P13 instead of P14. Explain how you would modify
LedOnOff.bs2 on Page 48 so that it will make your LED circuit flash on and off
four times per second.
flash on and off 5000 times before it stops. Hint: you will need to modify just
two lines of code.
Make the bi-color LED start out red for 3 seconds. After 3 seconds, change the
bi-color LED to green. When the bi-color LED changes to green, flash the
yellow LED on and off once every second for ten seconds. When the yellow
LED is done flashing, the bi-color LED should switch back to red and stay that
way.

lower values allow more current to flow.
connect 4 wires by plugging all 4 wires into the same row of 5 sockets.
