Hi
I'm currently trying to build a little robot with 4 hacked servos My problem is just that when i try to drive 4 servos it stalls. I have no problem driving 2 servos like others do, and i have even tryed to make a paralell coupling of the servos with 2 servos on each dataline but with no luck
Yesterday i tryed to make a driving circuit with a BC547 and connect it like this:
Base i coupled to the dataline with a 2,4K resistor Collector is connected to a 2,4K resistor to +5v and Emitter is connected to ground
i connect the signal line from the servo to the collector pin of the transistor ( hoping it would work ) but it didnt :-(
What am i doing wrong ??? can anyone help please !!
Thanks in advance /Thomas Krogstrup
