Robotic Arm With Zio Modules Part 3

This blog post is part of the Zio Robotics Series.

Introduction

In our previous blog, we posted Part 1 and 2 tutorial on how to control a Robotic Arm using Zio modules.

Part 1 mostly concentrated on automatically controlling your Robotic Arm’s Claw to open and close and only utilizing one servo.

Part 2 uses a Wireless PS2 Controller to control our Robotic Arm and utilizing all four servos.

In today’s tutorial, we will continue with the previous Robotic Arm setup Part 2 to build an App Controller that leverages on BLE Technology and control our Robotic Arm via that App interface.
