A step to combine the technology and spiritualism.

A step to combine the technology and spiritualism.

This project demonstrates the use of electronics and embedded system with Chakra Meditation.

This is my step to put forth to help a yoga institution and to create an awareness about Chakra healing.

Step 1: Parts and Material


Arduino Uno x 1

Relay Module x 7

Arduino MP3 Shield x 1

Speaker: 3W, 4 ohms x 2

RGB LED panel x 7

Step 2: Hardware


I had cut the Plywood to the required dimension and Glass to cover each RGB LED Panel.

The 12V adapter is installed for powering the device and a separate adapter is used to light the LED Panel. The Relay Connections are used to switch the LED Color Panels. Make sure that the supply is isolated.

Drill the plywood to mount the PCB.

Step 3: Connections


*Arduino -> BT MODULE*

TX -> RX

RX -> TX

VCC -> 3.3v

GND -> GND

*Arduino -> Relay Board*

IN1 -> A1

IN2 -> A2

IN3 -> A3

IN4 -> A4

IN5 -> A5

IN6 -> A6

IN7 -> A7

VCC -> VCC

GND -> GND

*Arduino -> MP3Module*

TX -> D10

RX -> D11

VCC -> 3.3v

GND -> GND


Step 4: Code

You can find the code below

Step 5: Connections

You can find the connections below

Step 6: Application

For now we will use the ready-made application. In the following days I will publish the application once after the certificates are processed.
