Top 23 C++ Arduino Projects

  • Marlin

    Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.

    There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.

    Klipper by contrast is a breeze to read through[2].

    I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

  • arduino-esp32

    Arduino core for the ESP32

    • Project mention: Any good/worthwhile Camera sensor modules for arduino/pico for still photography? | /r/diyelectronics | 2023-12-11

    You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.

  • WorkOS

  • 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

  • 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: I built an offline smart home, and why you should too | news.ycombinator.com | 2024-01-11

    I am planning to do this soon(TM).

    Probably starting with ESPHome to control my heat pumps over IR.

    The remote works but I forget to turn it off when not in one of the rooms, and it can't do smarts like keeping temperatures in desired bounds.

    An ESP32 running ESPHome with high power IR LED, a presence sensor, temperature sensor, and some pre-built library to control heat pumps[1]. it looks like it should be fairly simple to implement with Home assistant.

    Now if I could only disable the beep from the heat pumps receiving commands.

    I would like to do smarter lighting, but the lack of decent smart light switches that support local control and are also licenced for use in AU are a blocker there.

  • 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?

    • Project mention: I Tested an HDMI Adapter That Demands Your Location and Spams You with Ads | news.ycombinator.com | 2023-09-29

    Agreed. If you want to prove to yourself that this vulnerability is real, consider that you can replicate the hypothesized malicious device you describe by taking a WiFi Duck https://wifiduck.com/ and combining it with a regular lightning-to-HDMI adapter by plugging the WiFi Duck into the extra lightning port on the HDMI adapter. All that would be needed to use this attack on an unsuspecting victim would be to combine the WiFi Duck and the HDMI adapter functionality into a small enough circuit board to fit into the Apple-style white enclosure.

    While there are other VR gloves discussed on reddit. They all seem to very bulky [1] [2] [3] and maybe are not being developed by computer engineers? It seems like there are 2 main problems.
