DIY Arduino & Bluetooth Controlled Robotic Arm Project with Circuit Diagram & Output

DECEMBER 22, 2017 BY RAVI 12 COMMENTS

In this project, I’ll show you how to build an Arduino & Bluetooth Controlled Robotic Arm using Android Phone. This Robotic Arm can be operated in either manual mode or can be programmable to be operated in Fully Automatic Mode.

You have already seen one Robotic Arm project from Electronics Hub, which we did everything from scrap (except for the motors and Arduino). We got very good response from you guys for that project and based on that we decided to make a better version of it, Version 2.0, if I must say. 

Before reading further, try this SIMPLE ROBOTIC ARM USING ARDUINO. 

This DIY Arduino & Bluetooth Robotic Arm Project is operated using an Android Phone over Bluetooth Communication. We have developed an Application for Android Phones, using which you can control the Robotic Arm for manual operation or program it for fully automatic operation. I’ll explain them in the later sections.

Circuit Diagram of Arduino & Bluetooth Controlled Robotic Arm

Let us start with the circuit diagram of the Arduino & Bluetooth Controlled Robotic Arm Project. The following image shows the circuit diagram with all the necessary connections.

The circuit diagram seems very simple but the construction part of the Robotic Arm is a little bit complicated.
