Back Saver Backpack carrying follower robot

Story

A Sparkfun Red-Board utilizes a LV-Max Sonar component to judge distances between the user and the robot, powering the DC stepper motor to move forward, reverse or change direction. Each motor requires around 5V to operate.

In the future, a feature using the TellMeWhen Relayr app and the Wunderbar proximity sensor will send a notification to an Arduino 2.0 BLE shield when the proximity threshold is violated, overriding the LV-Max Sonar readings.
