Ps2 controller to servo

Help & Support Robot Parts
1

Hello,

I am very new at this so please forgive me. I am trying to make a stand alone Lynx B - Pan and Tilt Kit (Black Anodized) pan and tilt system that is controlled by a ps2 controller

I have tried to wade through all the info on the site but I seem to be overwhelmed
I have already purchased the wireless PS2 Robot Controller and the Sony Playstation Controller Cable I t was quite obvious that out of the box these will not run my hobby servos.

Please tell me what else I need. I’m guessing I need some type of motor controller or bot board…please let me know what I need to purchase…I hope not to have to do any programming because I have no clue about it at all.
Is there a simple out of the box way to simply control a hobby servo with the ps2 controller…I’m willing to buy whatever I need to

sample code to run on BasicATOM IDE:
I HAVENT TESTED IT BUT IT WAS USED IN ONE OF MY OLDER PROJECTS, IV JUST REMOVED SOME PARTS OF THE CODE THAT WILL BE OF NO USE TO YOU AND LEFT YOU WITH THE PAN AND TILT PARTS.
SORRY IF ITS NOT COMPLETE, BUT IT WILL POINT YOU IN THE RIGHT DIRECTION. I ALSO KNOW THAT YOU CAN PROGRAM WITH OUT THE ssc-23 AND JUST USE THE botboards. MIGHT BE WORTH LOOKING INTO IT.

If you get the BotBoard II and the Basic Atom 28 you will have what you need to do it. I don’t have a program for just a pan and tilt though. If no one can throw something together I will try later.
