  • IRremoteESP8266

    Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/

    Project mention: Struggling to get IR transmitter working | reddit.com/r/esp8266 | 2022-10-13

    First, try to remove the resistor(i was made an ir remote using the top circuit for ir sender). check the components, maybe one of them are dead. Second, check the gpio and config. Third, maybe the problem is the code. Maybe you should try the original IRRemoteESP8266 library first: You should checkout the original esp8266 ir remote library first: https://github.com/crankyoldgit/IRremoteESP8266 checkout my project: https://github.com/KD-MM2/MHI-AirCon-ESP8266/blob/main/Ver-1_Webserver_IRRemote/TurnOnMitsubishiHeavyAc.ino

    A suite of WiFi/Bluetooth offensive and defensive tools for the ESP32

    Project mention: Flipper Zero hacking multi-tool | reddit.com/r/Hacking_Tutorials | 2022-11-14

    I bought the Flipper zero hacking multi tool when it first came out to experiment with cloning sub GHz remotes, and looking into the different encryptions that things like garage door openers and things like that have. I found the tool really easy to use with the custom firmwares that are out there (https://github.com/justcallmekoko/ESP32Marauder/wiki/flipper-zero), tutorial(https://www.youtube.com/watch?v=_YLTpNo5xa0).

    Project mention: Anyone want to help create a Free and Open Source AlphaSmart Neo? | reddit.com/r/AlphaSmart | 2022-08-26

    Some ideas can be borrowed from here: https://github.com/fdivitto/FabGL

  • TaskScheduler

    Project mention: How do you make a code that does like 2 or 3 things simulatneously? | reddit.com/r/arduino | 2022-09-13

    When you get a little more advanced it's not hard to extend the BWD code to hsndle any number of "time when something should happen". Or you can use something like the TaskScheduler library.

  • Control-Surface

    Arduino library for creating MIDI controllers and other MIDI devices.

    Project mention: Hello my fellow logic lovers, I have a question. What is the best DAW-Controller for logic, or would you recommend getting an iPad and using logic remote? | reddit.com/r/LogicPro | 2022-07-12
  • ESP32_BLE_Arduino

    The library source for the ESP32 BLE support for Arduino.

  • AutoConnect

    An Arduino library for ESP8266/ESP32 WLAN configuration at runtime with the Web interface

    Project mention: Bluetooth or WiFi for apps? | reddit.com/r/esp32 | 2022-08-30

    And for Wifi management on ESP32, this awesome repo that "does it all": https://hieromon.github.io/AutoConnect/ -- this repo creates its own access point you can connect to with your phone to pop-up a "captive portal" (like you see at hotels or airports) to enter your own Wifi credentials -- this is only done once -- after that, the ESP32 will connect to the last known good Wifi network. If you don't want that, just use the built-in Wifi functions to create a local Wifi hotspot to connect to. Then creating web pages on the ESP32 is easy -- you can use the "PageBuilder" JSON syntax, or host regular HTML/JS/CSS files on the SPIFF/LittleFS partition and server those in response to incoming requests.

  • async-mqtt-client

    📶 An Arduino for ESP8266 asynchronous MQTT client implementation

    Project mention: Messagebus | reddit.com/r/esp8266 | 2022-06-21

    Most definitely! I'm using https://github.com/marvinroger/async-mqtt-client this to connect all my esps to a shared message bus.

  • HomeSpan

    HomeKit Library for the Arduino-ESP32

    Project mention: Homekit BLE communication | reddit.com/r/esp32 | 2022-08-23
  • ESP32-A2DP

    A Simple ESP32 Bluetooth A2DP Library (to implement a Music Receiver or Sender) that supports Arduino, PlatformIO and Espressif IDF

    Project mention: Outputting the AudioPLL to an external DAC | reddit.com/r/esp32 | 2022-11-21

    For all other i2s pinouts, I'm leaning on this GitHub-project: https://github.com/pschatzmann/ESP32-A2DP

  • ESPresense

    An ESP32 based presence detection node for use with the Home Assistant mqtt_room component for localized device presence detection.

    Project mention: Cool Home Automation Ideas | news.ycombinator.com | 2021-12-24

    What i found to be semi-reliable is something like room-assistant or ESPresense - however, you need to have some kind of Bluetooth device/wearable on you to be able to really get room-level reliability...

    https://github.com/ESPresense/ESPresense

  • ESP32-audioI2S

    Play mp3 files from SD via I2S

    Project mention: Is it possible to stream audio from a web server to an ESP32? | reddit.com/r/esp32 | 2022-10-09

    I think the best way is to use a I2S amplifier, and a library like this: https://github.com/schreibfaul1/ESP32-audioI2S

  • ESP32-HUB75-MatrixPanel-DMA

    An Adafruit GFX Compatible Library for the ESP32, ESP32-S2, ESP32-S3 to drive HUB75 LED matrix panels using DMA for high refresh rates. Supports panel chaining.

    Project mention: Just finished this rebuild from original to ESP32 | reddit.com/r/cade | 2022-11-06

    I'm about to share the whole project documentation in german. I used ESP32-HUB75-MatrixPanel-DMA with additional 74HC245 to shift the levels up from 3.3 to 5v (as there is a 2m flat cable running through the frame to the display). The Library is based of Adafruit GFX, for which you can find plenty of examples. If you don't want blanking, use two buffers or partially repaint (for the text and image animation I added black filled boxes on each redraw before painting the new position/text). The ESP32 has just enough pins to power the basic functions, but I'm about to order a new PCB with a portexpander, which frees some pins and allows for blinking buttons. Will add a DFPlayer Mini as well, as soon my customer decided, which MP3 files he wants.
