## What it is
An ESP32 Arduino project that turns the microcontroller into a basic oscilloscope, sampling GPIO signals and displaying them in a web browser interface. It serves an HTML UI over WiFi and supports digital (0/1) and analog (0-4095) signal visualization.

## Use cases
- view GPIO signals from an ESP32 in a web browser
- debug digital and analog signals on ESP32 pins
- monitor sensor waveforms without dedicated oscilloscope hardware
- build a cheap DIY oscilloscope with an ESP32 board
- inspect signal timing on embedded projects over WiFi

## When to choose
- you already have an ESP32 and want a quick low-cost signal viewer
- you need remote/browser-based monitoring of ESP32 GPIO signals
- you want an Arduino IDE-friendly oscilloscope demo or starting point

## When to avoid
- you need accurate, constant sampling rates or high-frequency signal capture
- you need professional oscilloscope features like triggering or precise voltage measurement
- your project is not based on ESP32/Arduino hardware

## Facets
- artifact type: application
- maturity: active
- function: monitoring, data-visualization, http-server, embedded
- domain: embedded-systems, hardware, developer-tools, iot
- platform: embedded, iot, browser
- tags: esp32, arduino, oscilloscope, electronics, signal-viewing, wifi, web-server
