I've recently grown interested in electronics and robotics, so I wanted to move my contraption using a servo motor. A 555 chip creates a PWM signal for servo for positioning, and I control the servo with a variable resistor.
I'm sure it will be able to move my contraption with ease, but I'm not comfortable putting 3 A through the breadboard (which would happen if the servo stalled).
Would something like the following work?
I believe this would route power required by the servo around the breadboard so breadboard would only work with the current required for controlling the servo motor, for creating PWM.
