Set Up For Step Motor with Easy Driver and Multiple (6+) Servo Motors on a Board

Hello Everyone! I'm having trouble connecting all my devices to my UNO and breadboard. I want to connect a step motor, Gikfun EasyDriver Shield Stepper Motor Driver, Stepper Motor NEMA17 12V 350mA, and (6+) FS90R servo motors to a breadboard. Also with this many devices is it okay use the Arduino's power or an external power? :confused: Please let me know. I would really appreciate it!

Use external power without a doubt

Hi,
I hope you are going to write your code in stages.
One output device at a time, only going to the next stage when the current stage is working, this will mean you have control of bugs in your code and learn at the same time about code interaction and layout.

Have you drawn a basic ciruit diagram to see if your have enough I/O for the Arduino.

You will definitely need a separate power supply , but bfe tyou do, check all your output devices for current and supply voltage needed.
