Hi there. First of all, I'm a newbie - sorry if my question seems stupid or something...
I've soldered together the PCB and programmed it with a short servo & LED test. The diode worked ok, but the servo wouldn't move. After figuring out it wasn't a software problem (2 hours of trying different pulse durations, damn...
), I tried checking the voltage, and on the servo pins it was around 1,7 V... On the sensor pins it was ok, slightly above 6 V (I power the robot with 4 AA batteries). I decided to solve the problem the hard way and plugged another 4 AA pack into one of the remaining servo pin sets. It worked, but that's a solution I'd hardly call elegant...
So - any other suggestions how I could get the servo to move? Will replacing the original 4 AA pack with 6 AA work? What would happen if I altered the voltage regulator connection (the tutorial says that servos are powered by unregulated input, while regulated output goes to the microcontroller) - could I simply remove the connection between the regulator input and the servos, and power both the servos and the microcontroller from the regulator output?
Again, sorry if this seems dumb - I suppose I could find the answer myself if I remembered my physics lessons, but junior high was a long time ago...
