Chakra Healing Harmonizer Using Arduino

• Arduino Uno x 1
• Relay Module x 7
• Arduino MP3 Shield x 1
• Speaker: 3W, 4 ohms x 2
• RGB LED panel x 7

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

The 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.

Prototype

Working on this Project:

You can find the entire code on my GitHub repository: https://github.com/Rahul24-06/Chakra-Healing-Harmonizer-Using-Arduino

To test the real-time scenario, we deployed it in one of the yoga meditation halls to test how possibly it could be used and the results were pretty good.
