Spray Paint And Other Parts Are Optional.

Step 2: Create the PCB

Create A Custom Sized Through Hole PCB By Cutting It in the Dimensions Of 17 cm* 2.3 cm Feel Free To Smooth The Edges And Sides With Sandpaper and Give a Curvature Like Shape Towards The Ends. Spray Painting The PCB With Black Spray Paint Gives It a Glossy, Shiny And A Good Look When The Assembly Rotates.

Step 3: Build the Circuit

Use the here presented schematic and reference pictures to create the circuit.

I have Made Use Of a Boost Converter As Well To Boost The Battery Voltage Of 3.7 V To 5 V.

Step 4: Final PCB

The Final PCB Should Somewhat Resemble As In The Aforementioned Picture, The Shaft Which Connects To the PCB can Be Connected Through the Rings Which Are Permanently Attached With The Help of Super Glue Or Araldite .

Step 5: Upload the Code

The Code Can Be Uploaded To The Arduino After Selecting The Arduino And The Port, The Code For Display Text Is Editable And Any Text Can Be Written/Uploaded To The Board. For The Purpose Of This Instructable I Have Uploaded The Text Instructables.
