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.
I believe [this](https://github.com/MarlinFirmware/Marlin/blob/2.0.x/Marlin/src/pins/sanguino/pins_MELZI_CREALITY.h) is my board, how would I identify the control_pin and sensor_pin in the configuration ?

Project mention: (esp32+adxl325+sdcard)Storing sensor data in sd card(in txt file) and then sending it to cloud. | reddit.com/r/IOT | 2021-10-16
I'd suggest sending data directly to AWS IoT Core (Free tier eligible) with the MQTT protocol. You can send data in JSON format. You could then use a serverless function to send that data to a DynamoDB (noSQL) database as the API is easy to use.

Scout APM
Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

Project mention: Create an access point with a server to set up a wifi connection | reddit.com/r/esp8266 | 2021-10-08
That sounds a bit like Wifi Manager. If it's not the same it might be worth investigating how they do it.
-
blynk-library
Blynk library for embedded hardware. Works with Arduino, ESP8266, Raspberry Pi, Intel Edison/Galileo, LinkIt ONE, Particle Core/Photon, Energia, ARM mbed, etc.
-
PJON
PJON® (Padded Jittering Operative Network) is an experimental, arduino-compatible, multi-master, multi-media network protocol.
Project mention: The operative system for a decarbonised, decentralised, digitised energy system | news.ycombinator.com | 2021-03-22When the physical layer of devices in the home don’t offer Wireless connectivity, hardware communication modules needs to be adopted to bridge the existing connectivity.
This protocol exists already is called PJON: https://github.com/gioblu/PJON

OpenMQTTGateway
MQTT gateway for ESP8266, ESP32, Sonoff RF Bridge or Arduino with bidirectional 433mhz/315mhz/868mhz, Infrared communications, BLE, Bluetooth, beacons detection, mi flora, mi jia, LYWSD02, LYWSD03MMC, Mi Scale, TPMS, BBQ thermometer compatibility, SMS & LORA.
Project mention: How can I use USB port from laptop to control IR transmitter module/circuit? | reddit.com/r/homeautomation | 2021-09-24An ESP32 dev board with OpenMQTTgateway can accomplish this. https://docs.openmqttgateway.com/

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: How can I control output pins of an ESP8266 via a linux terminal over wifi? | reddit.com/r/arduino | 2021-09-24Either write your own api to drive it via a pre-written library like crankyoldgits IRremote or flash something like tasmota-ir which has IR driver capability and a restAPI which would allow you to send raw codes or protocol specific hex codes from a script via curl. There's a good reason people use prebuilt solutions, modulating a 38kHz carrier with often complex protocols is not a trivial coding excercise on an MCU, thankfully there a number of dedicated/obsessive techs who have already done the heavy lifting and are generous enough to share the results of their hundreds or thousands of hours work with us lazy types who don't want to reinvent the wheel.

Project mention: I built a split-flap YouTube subscriber counter | reddit.com/r/arduino | 2021-07-31
This is based off the splitflap project, which includes ordering and assembly guides.

I'm trying to get acknowledgement payloads to work with an esp32 as the sender and an uno as the receiver. The code below works as a single way transmission, but uncommenting the commented code does not work. The example code works as intended but stops working when I try to modify the structs that contain the data, and I don't know why. How can I make my own code work?

Project mention: [OC] My Aang and Zuko Painting on glass. Thinking of putting colored LED lights on the wall behind the frame, do you guys think it would be a good idea? | reddit.com/r/TheLastAirbender | 2021-02-06
For libraries, I don't recommend the Adafruit neopixel lib. I think this is better, easier to use, more robust, and faster in ease of use and code execution. https://github.com/kitesurfer1404/WS2812FX

Project mention: MIDI-controlled LED strip on keyboard (WS2812B controlled by ESP8266) | reddit.com/r/somethingimade | 2021-09-30
It's the exact circuit on Wikipedia connected to a serial input on your microcontroller, read by the Arduino MIDI library, and then translated to LED using the FastLED library. MIDI pitches go from 0-127 - but even a full-size keyboard uses a max of 88 keys (the one shown in the post is 61-key), so you'll have extras.

NeoPixelBus
An Arduino NeoPixel support library supporting a large variety of individually addressable LEDs. Please refer to the Wiki for more details. Please use the gitter channel to ask questions as the GitHub Issues feature is used for bug tracking.
Project mention: How to decrease SPI clock rate for long string of APA102s? | reddit.com/r/WLED | 2021-06-13I see FastLED defaults to a 12 MHz SPI clock and the rate can be controlled via the DATA_RATE_MHZ template parameter to addLeds(). I am having some challenges following the WLED code, but it looks like the NeoPixelBus library handling the APA102 strips defaults to SPI rate of 20 MHz.

Project mention: Can I hand wire a keyboard using the ESP8266 instead of the Arduino pro micro ? | reddit.com/r/MechanicalKeyboards | 2021-07-30
ESP32 might work though: https://github.com/T-vK/ESP32-BLE-Keyboard

Or just use TaskScheduler and never have to worry about this again. https://github.com/arkhipenko/TaskScheduler

Project mention: Is there a market for bespoke home automation components? You may recall I built this interface to our home that speaks, rings, and lights regular alerts. It has tasmota at its heart so is hardware based and easily interfaced with Home Assistant. Is there a market for me to make this kind of thing? | reddit.com/r/homeassistant | 2021-01-22
Great news: you can build one yourself or you can buy one! :D
