This project demonstrates a simple WiFi-based client-server communication system using two ESP8266 microcontrollers. The client sends a base64-encoded message via HTTP POST to the server every 5 ...
Arduino IDE with ESP8266 board support installed. Set your WiFi SSID and password in both the client and server scripts. Make sure both devices are within the range of the specified WiFi network.
The ESP8266 is the answer to “I want something with Wifi.” Surprisingly, there are a number of engineers and hobbyists who have not heard of this chip or have heard of it but don’t really understand ...
It has never been easier to build displays for custom data visualization than it is right now. I just finished one for my office — as a security researcher I wanted a physical map that will show me ...
The ESP32/ESP8266 WIFI display using MQTT protocol project features several wifi modules suitable to IoT applications. These WiFi modules has OLED display integrated or connected particularly to the ...
This circuit allows you to drive a strip of WS2812 RGB LEDs (also called NeoPixels via Wi-Fi. Using the module ESP-01 module (featuring the ESP8266 chip), the board becomes a Wi-Fi access point. You ...
Abstract: A Wi-Fi wireless platform with embedded Linux web server and its integration into a network of sensor nodes for building automation and industrial automation is implemented here. In this ...
NeoPixel LEDs are cheap and easy-to-use RGB LEDs, digitally addressable. Example code, libraries and supporting content can be found easily everywhere. In the September-October 2018 issue of Elektor ...
