Anas Nashif 70758c4374 tests: fix test identifiers The seasonal overhaul of test identifiers aligning the terms being used and creating a structure. This is hopefully the last time we do this, plan is to document the identifiers and enforce syntax. The end-goal is to be able to generate a testsuite description from the existing tests and sync it frequently with the testsuite in Testrail.

PWM: Servo motor
################

Overview
********

This is a sample app which drives a servo motor using PWM.

This app is targeted for servo motor ROB-09065. With the PWM control signal, the
servo motor can rotate to any angle between 0 and 180 degrees. The corresponding
PWM pulse width is between 700 micro seconds and 2300 micro seconds. The motor
is programmed to rotate back and forth in the 180 degree range.

Since different servo motors may require different PWM pulse width, you may need
to modify the pulse width in the app if you are using a different servo motor.

Wiring
******

BBC micro:bit
=============

You will need to connect the motor's red wire to external 5V, the black wire to
ground and the white wire to pad 0 on the edge connector.

Building and Running
********************

This sample can be built for multiple boards, in this example we will build it
for the bbc_microbit board:
