Top 23 C++ arduino-library Projects

  • ArduinoJson

    📟 JSON library for Arduino and embedded C++. Simple and efficient.

    • Project mention: How can I obtain weather info? | /r/esp8266 | 2023-05-20

  • Arduino-IRremote

    Infrared remote library for Arduino: send and receive infrared signals with multiple protocols

    • Project mention: Connect to wand? | /r/MagiQuest | 2023-09-10

    However, there are plenty of libraries at this point which can handle the signal to varying degrees (some cant handle cast type but many dont care about that feature, including the game itself). I believe the most up to date currently is: https://github.com/Arduino-IRremote/Arduino-IRremote

  • InfluxDB

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

    Not built, but designed a widget with a rest api on a wifi endpoint on one side and an IR led on the other to automate my dumb a/c unit. There was already a library to emulate the exact IR remote control,

  • ESP32-BLE-Keyboard

    Bluetooth LE Keyboard library for the ESP32 (Arduino IDE compatible)

    • Project mention: ESP32-BLE-Keyboard Example - "does not name a type" error | /r/arduino | 2023-10-24

    I am trying to get started with the bluetooth keyboard example for ESP32. using the example, it throws the error: "Compilation error: 'BleKeyboard' does not name a type" I have tried to compile this in Arduino 1.8 and 2.2.1 and on multiple computers. all fail to compile. I even tried to downgrade the ESP32 package to 2.x to no avail. What am i missing here?

  • RF24

    OSI Layer 2 driver for nRF24L01 on Arduino & Raspberry Pi/Linux Devices

  • ArduinoJoystickLibrary

    An Arduino library that adds one or more joysticks to the list of HID devices an Arduino Leonardo or Arduino Micro can support.

    • Project mention: No Second hat switch with arduno Joystick | /r/arduino | 2023-11-15

    I'm at a good point with the code and the hardware, but I ran into this issue where the library says that you can define up to 2 hat switches, and I need to use both and here's the problem.
