Controlling Arduino Using Voice


Controlling a Maker UNO using voice seems difficult and impossible. But no worries, now we can control the Maker UNO using our voice with the help of Arduino Voice Control Apps and Bluetooth HC-06. This apps is free and available in playstore. Now let’s have a look on how to do it! 


This tutorial use :

  1. Maker UNO
  2. Bluetooth HC-06
  3. Red LED
  4. Green LED
  5. Yellow LED
  6. 220 ohm Resistor x 3
  7. Male to Male Jumper Wire
  8. Breadboard

You can make the hardware connection based on the diagram and table below.

HC-06 : VCCMaker UNO: 5V
HC-06 : GNDMaker UNO: GND
HC-06 : RXMaker UNO: pin 10
HC-06 : TXMaker UNO: pin 11
Yellow LED (+)Maker UNO: pin 4
Red LED (+)Maker UNO: pin 5
Green LED (+)Maker UNO: pin 6
Yellow LED (-)Maker UNO: GND with Resistor
Red LED (-)Maker UNO: GND with Resistor
Greed LED (-)Maker UNO: GND with Resistor
