kbaumen:
Thanks for the quick reply.Currently I don't have the calculations with me but the power supply is enough for this sort of testing. Currently the robot is just sitting on the bench and legs are moving freely in the air. Besides, if they were drawing more than an amp, the fuse would've burned out on the board. Of course for it to actually walk, we will need more current.
The board has its own battery to power it (or sometimes the USB cable connected to my laptop). So there shouldn't be any current sags when starting the servos.
Ok - it wasn't clear on the first post you were doing this (good idea, though!) - so, I would defer to dxw00d's suggestion (you might have to resort to using an analog input pin as a digital pin; though I would suggest going with a separate servo controller)...
