Arduino based serial servo controller

Step 6 Get creative!

Think of cool things to make with this. Some ideas:
1. Remote throttle for a car.
2. 3D camera mount
3. underwater rover

Have fun!!

quick question i have 2 servos controlled by a serial write and read system. do i have to have the arduino plugged into a computer or can i use an external power source(9v with barrel jack slot)?

Well, for the serial write and read to work, you'll need the USB connection (or another device to forward the serial data, be it bluetooth, Xbee, etc.)... so yes, it'll need to be connected to the computer somehow (if that's what you're doing).

However, as far as power is concerned.. it'll work as long as the servos aren't too big for the 5v regulator on the Arduino (although, even then it's not a bad idea to use a larger regulator separate from the Arduino's to run just the servos, I've seen some odd things happen when the servos get to be too much for the Arduino's power supply, but not enough to actually shut it down)
If it does need a larger regulator, you can use something like a LM317 regulator to supply power to the servos (or another regulator, I just happen to like the 317)
Thanks, Matt

Thanks it is not a power problem im just tryimg to end the dependance on my laptop but I guess it will take comeplete reprogramming :/
