Displaying Arduino data on website

arduino web

There are many ways of putting real world data to webserver. You can use third party services like cosm. But if you do like to keep everything under your control then do it simple way. Luca chares a tutorial how to do this using simple PUT and GET methods. For this he uses PHP pages to read data from Arduino with Ethernet shield and then display on webpage in your desired form. His example is based on reading SD18B20 temperature sensor. Data is stored in CSV file, but it is recommended to use database instead. But for demonstration purposes it is enough. Continue reading

Sending Tweets to Your Office Door Using an Arduino

One of the most common things you will find in offices and tables and walls are POST IT NOTES – people would like other people to know when they are out to lunch or on a vacation or even on the bathroom [if not in a hurry]. Its a brilliant idea to put adhesive on the back of small rectangular sheets of colored paper and have information written on them – there are two things I don’t like about these little messengers 1.) the more you post the more paper needed – thus more trees needs to be cut 2.) you cant update it – unless you are planning to erase then write a new note and how are you going to do it if your out of office? Erico Guizzo posted his answer to this question on an article at the IEEE spectrum – the solution was to use social media [Twitter] and available microcontroller hardware in unison to build an electronic POST IT that could hang in your door, could get updates from twitter and even show the… Continue reading

Send strings to LCD from web page

Arduino board and Ethernet shield can serve as basic web server. With limited Arduino resources you can run simple web pages where you can send variable data and also read them back to Arduino. This is convenient when you want to have convenient control panel and remote access. So following project actually is a simple demonstration how to enter couple text strings via web page and display them on LCD attached to Arduino. Code can serve as a good starting point for more complex projects. Continue reading

Try Arduino robot via Web interface

Yes it’s real. You can open a web page and start controlling this amazing robot hand. In the web page control panel you can move objects with robot arm or simply change light colors within RGB scale. You can Robot actions through web cam. Orbduino robot is callable and probably will be enhanced in future. Project is constantly updating by adding various new features and fixes. Core of robot is based on Arduino Duemilanove board equipped with Ethernet shield. Also there is a temperature sensor that allows reading room temperature. Locally robot is equipped with LCD, which displays messages of robot action. So hurry up to try this one, who knows how long it will be live. Continue reading

Get your beer cold with this fridge controller

So your fully stuffed with beer fridge thermostat broke and you have a nerdy look why not to fully computerize the process by your own. Arduino fits right well for this as you can easily control a compressor, log the temperature and even see what’s going on via web interface by using Arduino Ethernet Shield. So why waste a spare Arduino with Ethernet only for fridge controller? So Author plans on putting a bunch of additional temperature sensors around the house and monitor them conveniently in web interface. Possibilities are almost endless and all started with a broken fridge. Thumbs up guys! Continue reading

Geeky 3 meter clock system

Seems that Arduino rocks the world. More and more great projects appearing that are built around Arduino board. And this is great because it allows to focus more on creative things than on MCU routines. This project caught my attention because of its uniqueness – it displays a time on three analog panel meters. And this is not all this clock can do – it also updates itself by logging to SNTP time server via Ethernet Shield. Adafruit Proto Shield allows easy interfacing of analog panel meters. Arduino sends time as PWM signals where OP-AMP drivers scales them to display time correctly on panels. I think this is great project to make your working table even more geeky. Continue reading
