Project mention: Ask HN: What have you built with ESPHome, ESP8266 or similar hardware | news.ycombinator.com | 2024-04-27

Brought an inactive home security system onto Home Assistant using the below repository, so I can track everything from smoke alarms to motion, doors, and windows. I swear there's a niche business opportunity in retrofitting all these deactivated systems!

• flipperzero-mayhem

  6 448 8.5 C++

  Perfect companion for your Flipper Zero. ESP32 with WiFi, BT/BLE, micro-SD, camera+PSRAM, flashlight and extras: NRF24/CC1101, 3V/5V sensors

Project mention: Show HN: Visual vulnerability scan with ESP32-CAM and on-device model | news.ycombinator.com | 2023-09-23

Hi HN!

What if your FlipperZero could scan the scene visually to match payloads to target devices?

In this example project, we trained a tiny image classifier to differentiate between iPhones and RFID card readers from an ESP32-CAM feed. We show how to create custom model optimized to run in real-time on your MCU.

We're planning to integrate this example with the Mayhem project: https://github.com/eried/flipperzero-mayhem

What kind of devices would you want to identify? Feedback/thoughts are welcomed!

• LilyGo-T-Call-SIM800

  1 447 3.5
  

Project mention: Lilygo TTGO Tcall GSM issue and power | /r/esp32 | 2023-05-03

Check the manufacturer code examples link, they use the gpio pin 4, inside the utilities.h file.

• EspMQTTClient

  4 419 0.0 C++

  Wifi and MQTT handling for ESP8266 and ESP32

Project mention: Synchronize 25 ESP8266 to start playback of an audio file at the same time | /r/arduino | 2023-12-08

This is a perfect use case for MQTT, e.g. this library for ESP boards. Create a broker on the network (e.g. a Raspberry Pi running Mosquitto, and have all the ESP boards subscribe to a topic. When you want to play a sound, publish a message to the topic, and all of the ESPs should see it very quickly. You don't need to synchronize clocks any more because it's simply based on the timing of publishing a message.

• ArtnetWifi

  6 345 3.4 C++

  Arduino library for Art-Net (artnet) over WiFi, send and receive DMX data. Runs on ESP8266, ESP32, Pi Pico W, WiFi101 and WiFiNINA devices.

Project mention: Using Resolume Arena 6 and 2 ESP32s | /r/FastLED | 2023-06-23

ArtnetWifi being one of the most used, you can see that it combines universe byte and subnet byte here

  ezTime — pronounced "Easy Time" — is a very easy to use Arduino time and date library that provides NTP network time lookups, extensive timezone support, formatted time and date strings, user events, millisecond precision and more.

• ESP-WebOTA

  3 281 6.2 C++

  Simple web based Over-the-Air (OTA) updates for ESP based projects

• esp-rgb-led-matrix

  1 274 8.8 C++

  Full RGB LED matrix, based on an ESP32 and WS2812B LEDs.

Project mention: ESPHome | news.ycombinator.com | 2024-04-23

Since you're (seemingly) already familiar with Arduino, just use that as your framework. You can program the ESP32 in Arduino and access any library you're familiar with as well as handle Wifi.

You can buy an RGB matrix on Adafruit and they sell esp32 boards that can drive them directly,so it's essentially plug and play, no hardware knowledge necessary.

If you prefer to DIY but still need some guide, check out this project that documents both hardware and software to achieve what you want to do:
