Microcontroller programming exercises by practice on
Arduino:
Write a program that lights a green LED attached to pin 3. The
green LED should turn off after a button attached to pin4 has been
pushed and released 3 times. Each time the button is pushed it will
turn on a red LED attached to pin 7 and turn off a yellow LED
attached to pin 9. When the button is not pushed the red LED will
be off and the yellow LED will turn on. Assume the button is wired
active low.
