Help With Homework Board Compatibility Issue

I have been working on trying to get the article written by Jon Williams in Nuts And Volts
to interface a ps2 controller for weeks ofcource to no avail. I called parallax and

The Homework board has 220 ohm resistors in each of the outputs and may be causing the setup to malfunction

I try it without the 220's in the circuit and nothing happens!

But to get to the point, has anyone succesfully used a psx controller with a HomeWork Board? And if not... does anyone else know a way we could controll the robot

The robot is for Sience Olympiad's Robobilliards competion.

ps: I have used 2 different SONY DualSHOCK controllers
pss: The needed amount of buttoons are 4 drive buttons 6 arm buttons

I have!

That article is popular today ... I spoke with a customer by phone who was also having trouble with that project. He contacted me later to tell me that he found a broken wire. I feel pretty confident in the circuit and code -- double-check your connections. And the 220-ohm resistors on the BOE are not the problem, I am quite certain of that.

Hey! Science Olympiad?! Robo Billards?! Haha. That's my favorite event! Back to back gold medals, and state records! 47 seconds! Now as a 10th grader, I'm Div. B's assistant coach.

Why are you using microcontrollers for the event?

It was da clock

The inversion transistor was producin a bad wave!
I got a ttl hex inverter and it worked perfectly

the microcontroller allows us to preprogram arm positions.
