Project Perspective

An eGas Gauge for my eBike is the fundamental and innovative "Energy Interaction" bridge for modern electronics developers. By focusing on the essential building blocks—the ampere-hour-to-capacity mapping and your high-precision analog-to-digital current sampling—you'll learn how to orient yourself and automate your first range-tracking session using specialized software logic and a robust basic setup.

Technical Implementation: Ampere-Hours and Current Shunts

The project reveals the hidden layers of simple sensing-to-energy interaction:

Identification layer: The Current Shunt Circuit acts as a high-resolution spatial eye, measuring each point of the current flow via its internal voltage drop.
Conversion layer: The system uses a high-speed digital ADC (10-bit) to receive high-speed current packets to coordinate mission-critical sensing tasks.
Visual Interface layer: A Custom Display / Status LED provides high-definition visual and mechanical feedback for your status check (e.g. Current Level, Remaining AH).
Communication Gateway layer: A DPDT Switch provides a manual parameter-override or autonomous status check during initial calibration to coordinate status.
Processing Logic logic: The ATtiny85 code follows a "coulomb-counting-dispatch" (or gauge-dispatch) strategy: it interprets analog voltage signals and matches battery levels to provide safe and rhythmic range performance.
Communication Dialogue Loop: Note codes are sent rhythmically to the Serial Monitor during initial calibration to coordinate status.

Hardware-Transportation Infrastructure

ATtiny85: The "brain" of the project, managing multi-directional current sampling and coordinating power and LED sync.
Current Sensing Array: Providing a clear and reliable "Measuring Link" for each point of battery energy.
Battery Pack (eBike): Providing a high-capacity and reliable physical interface for your first successful "Transportation Mission."
Capacitors (2.2uF/10nF): Essential for providing clear and energy-efficient protection for every point of signal filtering and stability.
DPDT Switch: Essential for providing a clear and energy-efficient digital signal path for all points of your data sensing array.
Micro-USB Cable: Used to program your Arduino and provides the primary interface for the system controller.

Interaction Hub Automation and Interaction Step-by-Step

The proximity-driven gauging process is designed to be very user-friendly:

Initialize Workspace: Correctly seat your sensors and ATtiny85 inside your eBike chassis and connect them properly to the battery line.
Setup High-Speed Sync: In the Arduino sketch, initialize analogRead() and define the sampling frequency in setup().
Internal Dialogue Loop: The station constantly performs high-performance periodic data sweeps and updates range status in real-time based on your location and settings.
Visual and Data Feedback Integration: Watch your gauge automatically become a rhythmic status signal, pulsing and following your location settings from a distance.

Future Expansion

OLED Identity Dashboard Integration: Add a small OLED display on the bike to show "Current Voltage" or "Battery (%)."
Multi-sensor Climate Sync Synchronization: Connect a specialized "Bluetooth Tracker" to perform higher-precision "Local Paging" wirelessly via the cloud.
Cloud Interface Registration Support Synchronization: Add a specialized web-dashboard on a smartphone over WiFi/BT to precisely track and log the total social history.
Advanced Velocity Profile Customization Support: Add specialized "Machine Learning (vCore)" to the code to allow triggers to be changed automatically based on the user's height!

eGas Gauge is a perfect project for any science enthusiast looking for a more interactive and engaging transportation tool!
