Introduction: How to Make Voice Controlled Robot
Do you Ever wanted to operate things on your voice ?
Then your at right place
you can control any things by using arduino, you just have to connect those things
and have to declare in program .
I made a simple voice controlled robot but you can connect any thing to the bot,
you can also make a home automation project just by using relay board
and changing some things in program (I mean you have to declare more things in program if you want to make home automation )

Step 1: Gather the All Parts and Tools
1 x Arduino Uno
1 x HC-05 bluetooth module
1 x L293D motor driver
few jumper wires
and robot chasis
2 x LED
tools you need-
or you can order from below link -

arduino nano - https://www.banggood.com/ATmega328P-Nano-V3-Contr...
or you can used arduino uno - https://www.banggood.com/ATmega328P-Nano-V3-Contr...

Step 2: Connections of Parts
Connect 4 jumper wires to HC-05 bluetooth module.
Plug in Tx pin of bluetooth module to Rx pin of arduino
and Rx pin of bluetooth module to Tx pin of arduino .
Connect pin 6 and 7 of arduino to Left motor (IN) pin of L293D motor driver
and connect pin 8 and 9 of arduino of Right motor (IN) pin of L293D motor driver.
Connect left motor (OUT) pin to left motor of your robot
and Right motor (OUT) pin to right motor of your robot.
Connect pin A0 and A1 to anode of two LED's and connect cathode of both to Gnd pin of arduino .
If you want to add extra things on your robot, then just declare pin in arduino code .
