Things I forget to do!! lol

Have you ever worked on a project or tried to trouble shoot some sort of complex technical thingy and cant figure out why its not working like it should? If your reading this most of us have some sort of problem like this. Recently I have been working on trying to get my NXP Mbed Challenge up and running and working on the last few hardware requirements. This last week i have been trying to get my servos and motors working together and have started to make some good progress. until i hooked up power. Servos would not move nor did they seem like they were even powered……double checked them with an arduino and they worked. So i put it all back together and tried again, still no movement from the servos, now i start all over again with the trouble shooting, I did this about 3 times tracing out all the wires, doing electrical conductivity tests, the whole 9 yards. After a few hours and a day of rest i went back to it………
re-connected everything back up and tried again…………And this is what I concluded ……

Always double check your ground wires, and make sure they are all connected, since I was using 2 boards, one was the servo power and distribution, the other was the uC, if the ground wires are not connected it will not work, at least for me lol….
