Top 23 C++ Esp32 Projects

  • GitHub repo 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.

    Project mention: Linear advance algorithm | reddit.com/r/MarlinFirmware | 2021-06-08

    As a side note: I can't recommend enabling HybridThreshold. Had some issues with layershifting (i.e. skipped steps) and disabled it again yesterday as I found this. Test ongoing.

  • GitHub repo ArduinoJson

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

    Project mention: Are there any guides on how to use an ESP to fetch data from a Google Sheet? | reddit.com/r/arduino | 2021-05-18

    I work with JSON mostly. So you might want to have a look at https://arduinojson.org/

  • GitHub repo esphome

    ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems.

    Project mention: Introducing my TallyWhacker. A new smart home device designed souly to piss off my upstairs neighbor. | reddit.com/r/arduino | 2021-06-04

    Not OP, but I‘m assuming this is using ESPHome With it you can flash ESPs with custom firmware that you can configure through a YAML file. It uses MQTT to talk to HASS, usually mosquitto.

  • GitHub repo 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.

    Project mention: arduino uno with blynk app | reddit.com/r/arduino | 2021-04-30
  • GitHub repo OpenMQTTGateway

    MQTT gateway for ESP8266, ESP32, Sonoff RF Bridge or Arduino with bidirectional 433mhz/315mhz/868mhz, Infrared communications, BLE, beacons detection, mi flora, mi jia, LYWSD02, LYWSD03MMC, Mi Scale compatibility, SMS & LORA.

    Project mention: Smart button | reddit.com/r/esp8266 | 2021-04-12

    A single ESP8266 running OpenMQTTGateway is capable of sending the commands that would otherwise have been sent by the physical remotes.

  • GitHub repo 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: Making dumb LED strips smart. | reddit.com/r/esp8266 | 2021-04-21

    Your starter for 10 on ESP8266 and IR is crankoldgit's library When you say transistors I hope you mean big beefy power transistors or mosfets? The current led strips use can be surprising, my 4.5m RGBW 12V strip draws 9A at full brightness and the similar length WS2812 would pull 15A at full brightness if my software didn't restrict it. Do run the numbers on power consumption in regard to your switching device. It's possible to do what you want with the existing receiver but as you've already found it's not that straightforward and requires a good magnifier and enough knowledge of electronics to decipher the circuitry before you could modify it, If you want a reasonable size prebuilt RGB controller the generic H801 boxes are cheap, readily available, ESP based and easy to flash your own code to. The other possibility is to IR enable your ESP8266 using a simple IR receiver like one of the TSOP series, the filters and amplifier are built in and as it's just a 5mm package it's easy to mount it where it's convenient. That way you can have the option of IR or WiFi control, I occasionally use an old IR remote as buttons are often more convenient than web pages for controlling things, in my case the remote talks to an IR to WiFi bridge I built using the library linked. above.

    Project mention: is it possible to use a one-button-bluetooth-camera-trigger with an ESP32?? | reddit.com/r/esp32 | 2021-02-06

    Maybe. Depends on whether the data between the Bluetooth pairs are encrypted. You could checkout some ESP32 Bluetooth sniffer examples, this may help you identify the camera trigger within the data stream. This may help https://github.com/justcallmekoko/ESP32Marauder let me know if you crack it :)

  • GitHub repo ESP32-audioI2S

    Play mp3 files from SD via I2S

    Project mention: Is there a library for streaming uncompressed stereo audio from a device to esp which then can feed a amplifier (digital, analog or toslink)? | reddit.com/r/esp32 | 2021-01-09

    Have a look here: https://github.com/schreibfaul1/ESP32-audioI2S

  • GitHub repo dscKeybusInterface

    An Arduino/esp8266/esp32 library to directly interface with DSC security systems.

    Project mention: Ademco Central Office reciever manual | reddit.com/r/homesecurity | 2021-05-11

    If one doesn't like the $100 cost of Envisalink, with DSC systems there is open source software on GitHub that uses a $5 Wemos D1 mini board and another $1 worth of electronic components (couple resistors and a transistor) to interface directly to the KeyBus and then provides several methods of control.

  • GitHub repo Firebase-ESP32

    ESP32 Firebase RTDB Arduino Library

    Project mention: Google Cloud IoT recommendation for streaming data from serial device, then reading in near real-time? | reddit.com/r/googlecloud | 2021-05-01

    Thanks a lot - yes, RTDB is my main DB and I'm a fan. My question is the best way to get data from an ESP32 directly into Firebase RTDB. I was going to try this repo, but was wondering if there was an alternate way to do it using Cloud IoT (perhaps too heavyweight for my needs though?)

  • GitHub repo aWOT

    Arduino web server library.

    Project mention: Vanilla Javascript OTA | reddit.com/r/esp32 | 2021-04-14

    If so, here is an example from my own web server library. I think the HTML + javascript should work with the existing backend implemented with the WebServer library that ships with the core too. I does not have a progress bar or any other nice to have features but it's as simple as it gets.

  • GitHub repo ESP32-BLE-Mouse

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