I'm new to Arduino and haven't done any education in electrical engineering before, so this might be a very dumb question.
I'm busy with a project to control two servo motors with Arduino. Now yesterday I connected the wires incorrectly to the breadboard, so the wires started smoldering. I didn't connect the resistor correctly, so I guess that might have been the problem.
Now I replaced the wiring, but it's not working and I don't know if the software might be the problem or the breadboard need to be replaced as well. I cannot see anything wrong with the breadboard, but it was warm so I don't know if it might be burned from the inside? The wiring of the servomotors seems to be okay, so I guess that I don't need to replace those I hope.
Any tips about how to check everything is still working?
Or might it be a good idea to buy an LED and add it to the breadboard to ensure it's okay?
EDIT: I guess I found some code to check that the servomotors are still okay. Just add them directly to the Arduino and run some code: Sweep
One other question: one of the servomotors doesn't have a black, red and yellow cable but a red, brown and orange. How can I know which ones the same as yellow, red and black?
