Arduino Ethernet Shield tweets temperature updates

Following hardware components can be used for the project:

  • ??1x Atmel-based Arduino Uno/Leonardo Board (ATmega328/ATmega32u4)
  • 1x Ethernet Shield
  • 1x Mini-Breadboard
  • 1x DHT11 Digital Temperature/Humidity Sensor / 5K Pull-Up Resistor

In terms of software, they made use of the Arduino IDE, Adafruit’s DHT library and the Arduino Twitter library.

“We have the Arduino tweeting out updates every 15 minutes; this may be a bit much for some people so just alter the delay as needed,” he wrote.?? “We also added the Update # number to the beginning of the tweet as if you send the exact same tweet consecutively to Twitter it won’t be posted… and if the temperature doesn’t change often this may happen a lot.”

Is it interesting?  You can check out the project’s official page.

Microduino-W5500

Microduino released the new Ethernet module Microduino-W5500 which is based on the unique hardwired TCP/IP Ethernet Chip from WIZnet.

Features

  • Microduino-W5500 is a brand new all-hardware TCP / IP protocol stack network chip after W5100, W5200 and W5300. It is the best choice of the embedded Ethernet with lower power consumption and operation temperature as well as improved workmanship.
  • Adopting U-shaped 27-pin Microduino standard interface, Microduino-W5500 can be stacked with Microduino-RJ45 and be delivered ready to plug in, making it smaller.
  • With open source hardware circuit design, Microduino-W5500 is compatible with Arduino IDE development environment. 
  • With uniformed Microduino interface specification and rich peripheral modules, it is very convenient and flexible for Microduino-W5500 to quickly connect with other modules and sensors corresponding with Microduino interface specification.
  • 2.54mm (0.1 inch) pin pitch, compatible to pegboard.
[YouTube] Building an Arduino home automation controller

Control physical devices using an Arduino based home automation controller that connects to your network and lets you switch things on and off using a web browser. This episode shows the construction sequence of a controller that combines an Arduino-compatible board, Power-over-Ethernet, and relay driver shields to create a self-contained controller that can serve up its own web interface so you can click buttons in your browser to turn devices on and off.
