but after looking around, i saw that everyone who did this was only worried about making it work. and often resulted as a very hard to use system with only potentiometers to use as controllers. so in my attempt at this, i decided that it needs to be much more polished if it is ever to be something of use. so heres how i did it:
UPDATE! ive managed to shink it down into an entire atari themed mint tin! check it out here
Step 1 Get the stuff.
first off, we obviously need an Arduino, we are also going to need an atari joystick, a rs232 socket, a rca jack, 1Kohm resistor and a 330 ohm resistor, a switch for power, and something to cram all the guts into , i decided to use a busted digital tv receiver as my enclosure
Step 2 Hack the enclosure.
Step 3 Install the rca jack.
then we can drill a hole in the back of the enclosure for the rca jack to come through and then glue it in place.
Step 4 Wire the serial port
now we have to wire the serial port to the pins on the arduino so we can get input from the joystick.
so using the following pinout, connect the following to the corresponding pins on the Arduino
pin1 up, to Arduino pin 7
pin2 dn, to Arduino pin 6
pin6 fire,to Arduino pin 2
