PONGuino – Arduino & S65 Shield – 2 Player MiniGame
PONGuino game on the MirrorBot v3 Hardware
I wanted a playable game to show the possibilities of the Arduino plattform in workshops. Since I already have a S65-Shield built in a box with two joysticks, I wanted to use that MirrorBot hardware for presentation.
The most funny code I could find for the S65 Shield was a Pong game by
This mod uses one axis of two joysticks – or two potis connected to input pins to move the two bats of the two players up and down.
The AI and encoder codes were removed and replaced by a similar check:
PONGuino 2 players in action
If the joystick potis are moved up or down, they decrease or increase the y position value of the matching bat.
If you have a s65 shield and would like to run this code, you could connect two potis to input pins (e.g. 0,1) and try those. Thes bats ‘should’ move, if you move the pots out of the center position.
I included a veeery simple level system:
PONGuino someone got a point +
After each round a level int variable gets increased. This level var decreases a delay() (starting at 10 ms) in the main loop -that way, so the game gets faster, the more rounds you play ( 5 times).
🙂
….
PONGuino game intro screen
This game is minimal, but already fun to play.
At least a six year old friend of mine often asks to play it – again and again 😉
It’s interesting to see, how fast this micro system works. Very fast animations are not possible, because there is no double buffering for the LCD, but everything runs just fast enough to keep you (or a six year old) concentrated on the screen.

PONGuino Mini Game
Arduino Pong using S65 Shield - Mod by tk@synoptx.net 1.2010
original: http://www.codetorment.com/2009/11/11/arduino-pong-using-s65-shield/
mod: http://lab.synoptx.net/2010/02/12/ponguino-arduino-s65-shield-2-player-minigame/
+=
- 2 player with 2 joysticks (2x 1 y axis) or pots
- super simple levels (decreasing delay)
- intro & score screens
Just a trial to get to know the s65shield library, but nice gameplay ;)
ThanX to codetorment for the code!

I have read your thoughtregarding the Arduino. You definitely have put a considerable amount of effort into writing it. 🙂
Right now, I run a website that sells Arduino motherboards and their related accessories. They are all imported from overseas.
Finally, customers in Malaysia can own an Arduino. If you have a Malaysian friend, do inform them of this site.
Thank you very much. I will remember your help. Keep in touch.
