This quick tutorial comes from a request Antonio posted in a comment: how to change the default port the webserver is listening on.
This is the last post in this tutorial and it’s about an Arduino sketch that receives a text string from the serial port and displays it on your display with a scrolling effect.
After having published my previous tutorial, some users wrote me asking a way to send bigger images using Arduino and the ethernet shield. The guys who develop EtherCard library are rewriting the way it handles TCP packets, in the meantime you can get around this problem including in your HTML page references to images hosted by other websites:…
In my previous tutorial, you learned how to display a fixed text, coded and saved in Arduino’s program memory, on your display. Now you’re going to learn how to display dynamic text…
In this post, I’m going to show how to display some characters on your display…
A new blog post about my led matrix display with a first example about interfacing it with Arduino…
When I published my previous article about how to control a led using a webpage, I was asked for an example with more than one led. Today I’m going to show you how to control two leds with a more stylish webpage thanks to some images…
Few weeks ago I brought from SureElectronics a led matrix display. The product is made by 4 8×8 led matrices and an Holtek HT1632C controller: In this first tutorial, I’m going to show how to communicate with control chip… COMMUNICATION PROTOCOL HT1632C chip implements a protocol similar to SPI; you can control the chip through 3 pins: CS (chip select)…
When I published my first example about using Arduino as a webserver, many of you wrote me asking how to control Arduino using a web browser: in this blog post I’m going to show you how to control a LED from a web page.
