Servos and Arduinos

[Nimgg]

hi nerds!

i'm doing a prosject in school where i need 4 servos to work in patterns, but when i try to code this, the servo only twitch (even though i put it to 180degrees) anyone have som suggestions on how to make them actually move as i want?

Real servo only go 180 degrees. If I remember correctly you tell it what angle to go to.  

 

Try typing 90. 

 

Also for the love of arduinos and not frying stuff make sure it’s wired properly. You need an EXTERNAL power source to move the arduino motor. Arduino pins only handle 20 milliamperes. To spin the motor, it’d take too much current and burn the board. You need an external power source like a power bench. 

 

I’ll double check my source code for when I programmed a servo in a few hours if I remember. I’m not home right now.

i use an external psu and the wireing works with some codes, i will post my code when i get to my work computer tomorrow

Quote me for the future. 

 

Just as a resource, the following link helped me out:

You can read more information and this is where that link and another resource are but I found the above link more useful anyway:

Attach a file of your Arduino code, I'll verify it for you!

Remember not exceed 10.5 volts to avoid overheating, though anywhere from 7-12 is safe, I am saying this as a daily user of Arduino for small breadboard circuitry with sensors.
