Chakra Healing Harmonizer – Arduino Meditation

A step to combine the technology and spiritualism. Introducing the Chakra Healing Harmonizer – Arduino Meditaion Helper. 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.

Video Demo

Step 1: Parts and Material

  • Arduino Uno
  • Relay Module with 7 Relays
  • Arduino MP3 Shield
  • Speaker: 3W, 4 ohms x 2
  • RGB LED panel with 7 LEDs

Step 2: Hardware

First We will build the frame of the Arduino Meditaion center. Cut the Plywood to the required dimension and paste a Glass sheet cover each LED of RGB LED Panel. For powering up the device, a 12V adapter is installed and another adapter is used to light up the LED Panel. We use the the Relay for easily switching 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[AdSense-C]

*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: The Code

You can find the sample code below.

Step 5: Connections

Step 6: Application

For now we will use the ready-made application.Please check out the below video to know more about the usage of Chakra Healing Harmonizer / Arduino Meditation Device.

I will be adding more on this once certificates are processed.
