ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

Go to your computers/phones settings
Ensure Bluetooth is turned on

Prompt

Act as software engineer and help me build one file application. Here's what I want to achieve.

It is a web crawler, which searches for alien conspiracy theories, stores the URL of the theory. Give the theory a headline and also short summary. Then continues to other links from that page. It must 
remember visited sites, so it wouldn't go into circles.

Twitter allows users to download parts of their data, see How to download your Twitter archive.

But what's not included in that data dump is the usernames/handles of the people that you follow or are following you. All you get is account IDs which is just an internal number and so a bit useless when it comes to archival.

Here's a way to get that data (you need to know how to run stuff in the terminal):

Go to your Twitter profile in a desktop browser (Firefox or Chrome)
Right click on page → Inspect → Network tab
Click on the Following link (e.g. https://twitter.com/{yourusername}/following)
