Excellent. I'll give you more details and specifications.

We need I2C to work for this to function properly. For now, we can let user display any string or shape on the oled screen

We'll use the I2C display. That's the common one. Less wires.

This is I2C. It'll work

@ho-dor is I2C sensors working now?

Hello @kartikeysaran , without a device it would be challenging. But you can give it a try. 👍🏼

This is about producing waves; not observing. Do we have that feature?

Can you read and understand the **title** of this issue? You can also read the issue body if it's still hard for you to understand.
