There was a problem hiding this comment.
Works nicely with a standard MG995 hobby servo. Can be controlled in loops too in the REPL to do e.g. a controlled sweep.
One note: interrupting the servo signal (e.g. by pressing E-STOP or disconnecting the wire) has a chance of causing the servo to move if the pulse happens to be truncated. Currently this seems to happen abnormally frequently when using the E-STOP key so be aware.

Right now this supports only a single channel and a fixed minimum/maximum/update frequency (1ms/2ms/50 Hz). These restrictions can be relaxed in the future if this is desired.
This is a REPL-only applet (which in itself is a new category established in this PR). It doesn't feel like ther's a good way to make a CLI for servos, and having only a REPL makes snense here.
This applet can also serve as an example of a rather simple applet that follows the latest best practices.
