In the previous examples our servo turns to the set angle at its maximum speed. High speed is not always necessary and can damage the servo itself if the shaft hits an obstacle.
Let’s improve our patch by making the servo move more smoothly. To achieve that,
we’ll need to set the
VAL pin value along with a series of transitional
values. There’s a node for that, and it’s called
fade node is in
xod/core. This node returns a smooth series of
transitional values, so it will smoothen our servo motion.
TARGpin waits for a target value.
RATEpin is a number that defines amount of change for the transitional values per each second.
The output pin returns 0 at the start of the program. Then, it starts to move
TARG value by the
RATE steps. The value of the output pin is
saved, so if the
TARG value changes, the output will start to move to this
value from the last one returned.
Now, the servo will turn at a speed of 18° per second (0.1 = 18°).
