My project required the control of two servos. I wired them to the gnd and +5v lines from the board. One servo hit something and could not move. I think it drew far too much current and fried my board - with smoke too.
So, I'm thinking of trying again using two dedicated servo controllers. Can anyone recommend a good servo controller that: can be powered by something other than the board? Is smart and doesn't need too many lines from the board? Cheers :)
