Hey guys- we have a Halloween project we're working on and we need some help with the programming today.
We've built the catapult seen here: http://www.instructables.com/id/Arduino-Controlled-Catapult/
His code is all broken and doesn't work. We have 4 servos instead of 3, one controls a hopper that reloads the catapult. We also have an Arduino WiFi shield and want the catapult to fire when a user on Twitter mentions a particular hashtag. Please let me know if you can help out, we can pay via PayPal and communicate via Skype.
