do/while Loop
=============
A ``do`` loop works in the same manner as a :ref:`while
<arduino-while>` loop, with the exception that the condition is tested
at the end of the loop, so the ``do`` loop will *always* run at least
once.
This is the basic syntax::
do {
// statement block
} while (test condition);
Example::
do {
delay(50); // wait for sensors to stabilize
x = readSensors(); // check the sensors
} while (x < 100);
