# Project Overview

## Purpose

This project will create a small standalone information display using an Arduino MKR1000. The device is meant to provide quick access to a few important data views on an SH1106 OLED screen with very simple physical controls.

## User Interaction

Two buttons are planned:

- `Next`: move to the next available screen or option
- `Select`: confirm an option or trigger a context-specific action

The exact behavior can stay minimal at first. A practical initial version is:

- `Next` cycles through screens
- `Select` toggles a secondary mode when needed

## Minimum Feature Scope

The first usable version should include:

- Time screen for local time
- Weather forecast screen
- Temperature screen using the AM2302
- Humidity screen using the AM2302

## Suggested Screen Behavior

To keep the interface simple on a small display:

- Show one primary screen at a time
- Keep text large and readable
- Refresh local sensor data regularly
- Refresh network-based data less frequently than local sensor data
- Avoid cluttered layouts

## Data Sources

### Local data

- Temperature from AM2302
- Humidity from AM2302

### External data

- Local time
- Weather forecast

The exact source and synchronization method for time and weather can be decided later during implementation.

## Non-Goals For Now

These are intentionally out of scope for the initial documentation phase:

- Final UI layout details
- Library selection
- Network/API implementation
- Pin-level firmware implementation
- Power optimization

## Open Items

- Document exact wiring for the display, sensor, and buttons
- Decide how local time will be synchronized
- Decide where weather forecast data will come from
- Define how button behavior should work on each screen
- Confirm refresh intervals for sensor and network data
