Hill Run v2 code

arduino

The code. Change DUCK_PIN to 3 if you want to use an UNO instead. The code is pretty compact and clean, if I say so myself.

3  An improved version of hill  run with interrupts to make code better.
4  NOTICE DUCK_PIN IS 18 INSTEAD OF 4  because of interrupt capablilities!
5  Hill run, a fun game where you jump over  hills and duck under crows.
6  Wiring:
7  Arduino +5V to breadboard power bus
8  Arduino Ground to breadboard ground bus
9  Jump button with 10k pull down to  ground, and to digital pin 2, and other side to +5V.
10  Duck button with 10k pull  down to ground, and to digital pin 18, and other side to +5V.
11  Passive buzzer  with one side on ground and one side on digital PWN pin 5.
12  16x2 16-pin Lcd  screen with normal arduino wiring, as in the lesson for the lcd screen:
13    -K  to ground
14    -A to +5V
15    -D4 through D7 to pins 9 through 12
16    -E  to pin 8 
17    -RW to ground
18    -RS to pin 7
19    -V0 to potentiometer output,  for brightness, potentiometer is connected to +5V and ground
20    -VDD to +5V
21    -VSS to ground
