Hi,

i created a poorman's led matrix of 4x4 with only one shift register (74HC4094) and 16 led's smiley

only 3 wires to the arduino for full 16 led control

It can also display some 4x4 font's i created with a little program i also made - you can find more info on my blog entry.

Ok thanks!

What (maybe) could be added is a parameter that can tell whether the 'slowdown' is still in progress.

For instance i set 3 servo's in a batch to position 180 at a speed of 2 it will take a while before they reach this.
If i could tell the 'servo lib' that i started this batch it can monitor the slowdown on some kind of boolean that is set to false when i started the batch - when all parameters reached there final 180 state the boolean is set to true.
This way a second batch can be started and my robot can move a bit less choppy.

Is something like that possible? This way timing is still possible without potmeters or readnig the state of the servo's.

i'm currently using the VarSpeedServo library.

But is was wondering if the version that you can download from this thread is the final version?

And is there (maybe) a version where you can pass a millisecond argument that will ensure that the movement will take exactly <milliseconds> of time to complete?

Either way, i like it a lot, having control over my servo's speed-wise smiley
