Rover Build Update: Arduino + GPS + Servo = glitch

Rover Build Update: Arduino + GPS + Servo = glitch

In today’s learn as you go along lesson, hit a problem trying to integrate a GPS module on the Arduino with a servos connected to the board’s PWM pin.  The result was the servos would glitch about every second or so.  Doing some searching and based on some forum posts (here too), it looks like the solution is going to be a Servo Shield.  Offloading the PWM processing to the shield should hopefully alleviate the interrupt contention. Here’s a video…
