I am new to the EZ Robot Contorller and an hesistant to start using it until I understand a few things.
Am I OK to use an external power source such as a 'Wall Wort'? Does it have to be 'regulated'?
When do I need to use an H-Bridge?
Lastly, as far as Analog / Digital is concerned...If I am using a motor, stepper motor or servo, are they are considered Analog and therefore plug into the Analog side of the EZ B?
My main concern is NOT blowing this thing up.
I apologize for all the questions.
Any help is very much appreciated.

Hey there!
You can provide up to 14 volts DC to the EZ-B. The Wall Wort will work. It isn't a concern to be "regulated" because the VR is rated to a specific amperage and ohms law yadda dadda
... At any extent, there is a fuse on the board to prevent kaboom.
You will need to use an HBridge if you are powering DC motors. You can not connect a DC motor directly to any microcontroller. Motors draw way too much current for a microcontroller to powre. An HBridge acts like a relay between the two.
Analog is always input. There is a little write-up about it on the Tutorials page.
Digital is either input or output.
If you are using a motor or stepper motor, they would be connected to an HBridge and the HBridge would be connected to Digital Ports.
If you are using a servo, it would connect directly to a Digital Port with no HBridge.
:) Let me know if you have any more questions. You'll find the Tutorial page full of videos and explanations of things.
