I've been trying a project form 30 Arduino project for the evil genius. the one with the two servos and the laser. When I put servos on my board they act erratically moving in random directions constantly. So I tried loading the example from the servo library and run them one at a time and they behave. However, if I modify that code to run two servos like the original project they move erratically again. I'm using these servos https://www.sparkfun.com/products/10333
. Is there something I'm not considering?
