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
