This PCB is designed using EasyEDA which is an easy-to-use PCB design tool.
The PCB resembles the shape of the Avengers logo, which, if lit, illuminates the background, and eventually the logo is visible to everyone.
For demonstration, I have used the Arduino Nano microcontroller to drive the LEDs. The PCB is made such that it can work with an onboard ATiny microcontroller or an external Arduino as well. The code for driving the LEDs is provided in the GitHub repository: https://github.com/Manasmw01/RGB_Logo_Wall_Light
