I want to move a servo using the Asset shield.
I’ve setup a function, and call it, however nothing happens. The function returns the value provided for the angle, but the servo does not move.
The function is “sa” or ServoToAngle.
I had it setup on A1-A5, but it didnt work. Last try I’m doing is on D1, but no luck.

/* -----------------------------------------------------------
This example shows a lot of different features. As configured here
it'll check for a good GPS fix every 10 minutes and publish that data
if there is one. If not, it'll save you data by staying quiet. It also
registers 3 Particle.functions for changing whether it publishes,
reading the battery level, and manually requesting a GPS reading.

// You can also change this remotely using the Particle.function "tmode" defined in setup()
