 The San Francisco public transit system ([[https://​www.sfmta.com/​|MUNI]]) makes realtime prediction data available through [[http://​www.nextbus.com/​|NextBus]]. For this example, we will mount a small servo with an arrow connected to it in a box, making a prediction display suitable for the home. The San Francisco public transit system ([[https://​www.sfmta.com/​|MUNI]]) makes realtime prediction data available through [[http://​www.nextbus.com/​|NextBus]].

 NOTE:  I chose to use a servo small enough to be safely powered by the 3.3v provided by the Oak. If you need a larger servo, you will need a few more components (like an [[https://​en.wikipedia.org/​wiki/​Opto-isolator|optoisolator]] or a [[https://​www.sparkfun.com/​products/​12009|logic-level converter]]) to allow the 3.3v Oak to control a servo which requires higher voltage. NOTE:  I chose to use a servo small enough to be safely powered by the 3.3v provided by the Oak.
