Programming for arduino:

First assign your variables outside of either function. This will be 2 button states and 2 button pins.

Next in the void setup() function set serial communication to a 9600 baud rate. Also set your pins to be input pins.

In the void loop() function use an if/elseif/else statement to send button 1 is pressed, button 2 is pressed, or nothing is pressed.

* For extra credit instead of doing item 3 your program begins by sending The current count is at 0 over serial.

*Every time a button is pressed send over serial the new count.

*The count only changes once for each press of a button.(using a delay() function will not work if a button is pressed too quickly or for too long and should not be used in this exercise)
