Wtf does this do

go-lcd-clock is a small background program that drives an LCD display screen, turning it into a live information dashboard. Instead of just showing the time, it pulls in useful real-time data so you get a glanceable summary of things you might care about throughout the day. Once installed, it continuously refreshes the display with four pieces of information: the current date and time, your internet connection speed, and local weather conditions. It runs quietly in the background on your computer, acting as the bridge between your internet connection and the physical LCD screen. This would appeal to a hobbyist or tinkerer who enjoys building small hardware displays. For example, you might connect a small LCD panel to a Raspberry Pi, set this program running, and mount the screen on your desk. You would get a dedicated, always-on panel showing your network speed and the weather without needing to open a browser or check your phone. Because the project is written in Go, it is a single, self-contained program that is relatively lightweight and easy to run. The README does not provide setup instructions, specific hardware requirements, or details on how it pulls weather data, so you would need to look at the code itself to understand how to configure it for your own screen.

Yoink these prompts

Prompt 1
Help me understand the go-lcd-clock codebase so I can figure out which LCD hardware it supports and how to wire it to a Raspberry Pi.
Prompt 2
Look at this go-lcd-clock Go code and tell me how it fetches weather data so I can change the location or weather provider.
Prompt 3
I want to run go-lcd-clock on a Raspberry Pi with a 16x2 LCD. Help me read the source code to figure out the correct GPIO pin wiring and configuration.
Prompt 4
Help me modify go-lcd-clock to add a new data source to the LCD display alongside the existing time, weather, and network speed panels.
