Paddle control with Arduino
Post Posted: Tue Aug 20, 2019 10:43 pm
Hello everybody.

I would like to share with you the development I did several months ago according to what I read on your forum and Raphnet previous development (I'm a recent member and i cannot post the links...)

Arduino Nano have several advantages over PICs: size, cost and easy to be programmed without a chip programmer. Instead of making an enclosure with a 3D printer, all electronics and the potentiometer can be allocated inside a standard SMS pad. To do this, as you can see on pictures, I broke the PCB inside the pad for UDLR and I made a hole on the pad.
One key point is that the standard SMS pad does not have all cable for the DE-9 connector. So, I cannibalized a Megadrive/genesis one to use its cable.

Two interesting conclusions
1) It is an export paddle, but it works with games as Woody Pop and other JAP games
2) If you use an everdrive over a genesis, be careful to unplug the standard pad and to plug this device just during the game programming, because it is only recognized after the turn-on routine but not after a reset.

I tested it with the OutRun 3D directly over a SMS model 1, which is very funny because it changes to automatic gearbox since the second button is disable. I also tested with a Woody Pop over the SMS-II as you can see on my video. I don’t have these two games (and the Woody Pop is only a JAP one) so I programmed them using EEPROM, what I could also explain you on other post.

I hope you like it.
