Hi everyone,

So here is my question how do I use the A2D8 or A2D10 objects to
create lots of buttons(say 6 buttons per A2D line) which I can use to
trigger events, servo position changes and the like? An example of a
specific piece of code would be nice? I know this is possible I just
need a good example for a starting point. Thanks for the help.

Update on this... I have figured out an easier way to do this instead
using the oKeypadX object. I'm still pretty hazy about how to get the
different keys to correspond to specific servo position values so any
similar examples of this object being used to flag different objects
would be really helpful. What I'm trying to do with this isn't that
complex but I am pretty new to this. Essentially I'm trying to make a
30 button array which will control 5 servos, directing them to 6
specific positions. Thanks for the help in advance.

If you are set on using the A2D function.
One would first need to build a voltage divider referenced to say, 5V
line.
Maybe use 10, 250 ohm resistors this will result in 10 possible
voltage levels. Hence 10 switches
Add a 10K pull down resistor to the A2D. Connect one term of 10
switches to the same node.
Connect the other side of each switches to the resistors.

Maybe use oA2DX object to detect the voltages generated at the A2D
input as each switch is pressed.
Or maybe use oCompare object it's your choice.
There may well be other possibilities.
Good luck
Stan
