⚠️ ⚠️ ⚠️ ARTIK Cloud has been depcreciated by Samsung ⚠️ ⚠️ ⚠️ Here we create an ESP8266/32 based device that emulates a RGB LED light using NeoPixels, which connects to ATRIK cloud. ARTIK cloud connects to smart home assistants like Google Home, Amazon Alexa, etc. Connecting to Samsung ARTIK Cloud https://my.artik.cloud/ GitHub: debsahu/ARTIKCloud An application made for ESP8266 to comunicate with ARTIK Cloud Connects to ARTIK Cloud via MQTT SSL port 8883 ARTIK Cloud is connected to all assistant platforms, integration is seamless Compiles on ESP8266-arduino core v2....
The goal here is to control a “dumb” TV using virtual assistants via Home Assistant. We tap into the push button of the TV and use a transistor along with ESP8266 to mimic a button press. GitHub: debsahu/PegasusTV Goal: Control a “dumb” TV using virtual assistants via Home Assistant Features: Uses D2 to control 2N2222 transistor Control using Web and MQTT API Completely Async WiFiManager Captive Portal to get WiFi credentials (Compile with -DUSE_EADNS for ESP8266) Connect PIN_CTRL pin to base of 2N2222, collector to Probe and emitter to GND Hardware Software Overview Libraries Needed platformio....
Exploiting low light photography with long exposure to paint in thin air using NeoPixels LED strips. Here we send real-time data using the E1.31 sACN protocol to a ESP8266 code: https://github.com/debsahu/E131_PixelPusher that displays strips of pictures over time. These bright lights are registered on the sensors of camera yielding out of the world photos!
Here we try to push E1.31 UDP data received wirelessly via ESP8266 and pushed to NeoPixel in the fastest way possible. Other projects with E1.31 support: GitHub: forkineye/ESPixelStick GitHub: Aircoookie/WLED GitHub: toblum/McLighting I also demonstrate how to setup and use Jinx!, ledfx and xLights GitHub: debsahu/E131_PixelPusher Minimalistic Async code around Async E131 for ESP8266/ESP32 Completely Async Web-interface to set starting universe, unicast/umulticast, total number of universes WiFiManager Captive Portal to get WiFi credentials (Compile with -DUSE_EADNS for ESP8266) Subscribes to E131 multicast Connect RX/GPIO3 to DIN of NeoPixel strip, and any PIN (<GPIO32) specified for ESP32 Upload included firmware....

Demonstration on ESP8266 & ESP32 using SSL/TLSv1.2 two-way handshake with secured mosquitto broker. SSL is preferred way of encryption of communication between devices over the internet. Here we secure a mosquitto MQTT broker and connect to it via ESP8266 & ESP32 that do a two-way handshake.

Here is a tutorial on how to call RESTful API on ESP8266 and process the data using ArduinoJSON. This data is visually represented in a NeoPixel ring for easy tracking of 3 buses approaching a certain stop. This code also sends MQTT messages with the received data. debsahu/RESTful-Ride Using ESP8266 to call RESTful API from http://TheRide.org to get real-time BUS data Features: Easy to read interface Fast and Responsive Portable, i....
Idea To convert an automatic trash can into a smart one. Hardware Automatic Trash Can Wemos D1 mini (ESP8266) 2N2222 transistor Implementation Here we use an ESP8266 to tap into the pins and emulate a physical button press. The ESP8266 uses a code as described in https://github.com/debsahu/SmartTrashCan to emulate a Wemo Switch, which is detected by Alexa/Echo device as a switch. GitHub: debsahu/SmartTrashCan Dependencies Library Link Use Wemo Switch Emulator Library https://github....
Getting one’s hands on APDS9960 is very easy, that can be used to detect hand gestures. Here we use this sensor to control lights on Home Assistant based on a gesture observed on sensor.
