Hi all im trying to add a direct real time option to controlling servo movement on my mechanical claw project. right now im using string code and another program using case statements to control the servos position via the serial monitor. you type in a letter or an angle and press enter

the next step is to program the claw to be controlled directly. Push the left the right arrow key and servo1 rotates clockwise, release it and it stops.

is the using Processing or another program the only way to do this? i had a look at the website and it seems to be mainly graphics programming. does anybody know of a way to do this using just the Arduino?

Push the left the right arrow key and servo1 rotates clockwise, release it and it stops.

Which key is "the left the right arrow key"?

You can make Processing send one value when a key is pressed, and another value when the key is released. Using arrow key is difficult, but using alphabet keys is easy. 'A' means pressed, and 'a' means released, for the A key.

does anybody know of a way to do this using just the Arduino?

Take a look at your Arduino. Do you see a keyboard? Mine doesn't have one.

You can attach switches to the Arduino, and make things happen when the switch is pressed or when it is released.

Two things to work on. First is having the servos move slower than normal so they can be positioned accurately. Second is developing an interface on the pc to connect to the arduino. Might be possible with a web page interface using the mouse for control.
