MYAKU-MYAKU gps

## Introduction movie

## Story

The Challenge:

The Expo 2025 venue is huge and easy to get lost in. The iconic Grand Roof Ring, being a perfect circle, makes it hard to tell where you are.Even when you’re carrying a map, it’s easy to lose your sense of direction—especially when passing through the Quiet Forest Zone in the center of the venue.

The Solution:

To solve this, we created the MYAKU-MYAKU GPS using an M5StickC Plus and GPS Unit v1.1. It sends us the name of nearby pavilions via Discord as we walk around. It also maps out our walking path inside the venue—so we can always know where we’ve been and where we are.

## Devices Used

This project uses the M5StickC Plus and the GPS Unit v1.1 for M5Stack.

System components: Google Spreadsheet, Google Apps Script, Ambient, Discord

Device: Mobile WiFi Router

## Description

Each time a preset distance is traveled, the device sends latitude and longitude data to Google Spreadsheet and Google Apps Script.

The locations of pavilions are stored in the Google Spreadsheet. When we get close to one, a message is sent via Discord to notify us.

The location data is also sent to Ambient, which tracks and maps our walking path throughout the Expo 2025 venue.

## How the M5StickC Plus + GPS Works

• Pressing the A button forces the device to send the current location.

• The distance threshold for sending updates can be set with the B button. This value is stored in NVS (Non-Volatile Storage) and is preserved even when powered off.

• The screen displays:

• Latitude and longitude

• Number of satellites detected

• WiFi connection status

• Distance traveled

• The set distance threshold for updates

• The rotation of MYAKU-MYAKU’s eyes on the display indicates that the system is running.

Location data is logged to a Google Spreadsheet via Google Apps Script.

When we get close to a pavilion (based on data in the sheet), a message is sent to Discord.

The location is also sent to Ambient, which visualizes our entire walking path within the Expo 2025 venue on a map — serving as a personal tracker.
