Story
(Just A Rather Very Intelligent System)
This project demonstrates the use of different technologies and their integration to build an intelligent system which will interact with a human and support in their day to day tasks.
Step 1: Parts and Material
*Arduino -> Relay Board*
IN1 -> D2
IN2 -> D3
IN3 -> D4
IN4 -> D5
VCC -> VCC
You can find the sample code below.

//Voice Activated Arduino (Bluetooth + Android) //Feel free to modify it but remember to give credit
String voice;

Passionate Techie ! Robotics | Electronics | Programming Hey Geek! If you are in search of electronics projects, Arduino based projects or any Micro-controller based projects, this channel is for you. In this channel, we build electronics projects using the impressive and low-cost boards that are available today. If you are a maker or if you want to learn how to make your own Arduino projects and other interesting Robots, do subscribe the channel to be a part of this community. We develop our own hardware and software projects and will try to build something new. Don’t worry if you don’t know how to program. I'll share the algorithm if you face any difficulties.
