| 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.
