VOICE CONTROLLED COLOR CHANGING LAMP

VOICE CONTROLLED COLOR CHANGING LAMP 

( Using ARDUINO HC06)

Here we will make a RGB lamp which we can control by our voice command. We can control color, what we need.  It is easy to make it .Let us Start.

Needed -

SpareParts-

1. Arduino board (UNO)  
2. Breadboard(Optional)
3. Jumpers wires  
4. RGB led  Bluetooth module HC-06/HC-05
5. Android Phone (Any)
6. Data cable for programming.
7. PC for programming.

  Software-

   Arduino IDE –(on your PC)

Connections (Arduino Uno with HC06)

          1- VCC – to VCC of Arduino

          2-GND – to GND of Arduino.

          3- RX – to digital pin 0(TX pin) of Arduino.

          4-TX – to digital pin 1(RX pin) of Arduino. 

          NOTE-(connect RX & TX pin after uploading the code)

       

          Note- Here i am using LED common Anode .If need to use common cathode led you 

have  to  connect long led terminal to ground .  

 Procedure to download program (Bord & Mobile)-

1.   Make the connections as shown in the above image. Don’t connect the RX & TX pins WHILE/BEFORE uploading the code.

2.   Copy the code given below and past on it on new file on arduino IDE.

3.   Download the app called BT Voice Control/AMR Voice(It’s free). Here is the link

4.   Open the app AMR Voice app (It will automatically turn on the device’s Bluetooth). Go to options. Click on “Connect to Robot”. Choose the device – HC 05.

5.   When you are connecting to the Bluetooth module for the first time, it will ask you the password. Enter 0000 OR 1234.

6.    When the device gets successfully paired with the sensor, the LED lights on sensor will start blinking at a slower rate than usual.
