Web-controlled Window Air Conditioner Using an Arduino

The internet of things has come to my little apartment in New York City. After about a week of tinkering, soldering, and piecing together bits of code from here and there, I can now load a web page from any browser, see the current temperature in my apartment (and a graph of the last 12 hours), and turn the AC unit on or off with the click of a button. This was accomplished with an Arduino, the open-source prototyping platform and the community of artists, techies and hackers behind it. I’ll show you what it looks like, then I’ll show you how I put it all together (my code is at the bottom if you want to try it yourself!

Internet of things project: Connect Arduino to Ubidots and Android – Part 1 & 2

2018-08-01T13:39:13+00:00

This IoT project explores how to connect Arduino to Ubidots and Android. One important aspect in Arduino Internet of things programmin is how to connect arduino to internet and store date to IoT cloud platforms using arduino ethernet shield. This aspect is important because it is possible to store data in the cloud and then analyze it. Once the data, like sensor values, is on the cloud is possible to access it using smart phones and control remotely the Arduino board.

RobotDyn – Ethernet module – W5500, 3.3V/5V

2018-08-01T13:39:20+00:00

The W5500 Ethernet module can be used to provide your projects with internet connectivity. W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10 / 100 Ethernet MAC and PHY embedded. Supports 8 independent sockets simultaneously. The W5500 Ethernet module has a standard RJ-45 connection. Support 3.3V and 5V input voltage and logic level from SPI. Work with All AVR(Arduino) STM, ARM boards.

This W5500 is a Ethernet module that basic on the new type chip W5500, The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (Serial Peripheral Interface). W5500 suits users in need of stable internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, …, which has been proven through various applications over many years. W5500 uses a 32Kbytes internal buffer as its data communication memory. By using W5500, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller. It is possible to use 8 independent hardware sockets simultaneously. SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5500 SPI supports 80 MHz speed and the new efficient SPI protocol, so users can implement high speed network communication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and a power down mode.
