eDavid the robot painter excels in numerous styles

The line between art and technology isn't just being blurred, it's being erased altogether. Painting and sketching from photographs and life, for example, is a technique that is now being mastered by robots. The latest, called eDavid, combines a camera, computer vision software, and a standard welding robot arm to skillfully recreate (in a variety of styles no less) any image…

ATmega328 Overclock (30MHz)

Hello everyone,

This is more fun oriented project than something useful (or not) since ATmega328 was not designed for clock frequency above 20MHz (see datasheet). So, 30MHz is push it far from the limit. :)

Besides, I…

Arduino generated VGA (color) signal - Complete!

Hey guys,

By the picture above we can notice that the problem with the black area was solved, and now, the entire screen is filled, so we can print on any corner (640x480 @ 60Hz). The problem was the interrupt function, the time of calling and returning was taking so much time for an ATmega328, I…

WebServer for Arduino without EthernetShield (with PC/Apache/PHP)

Hey guys!

A lot of people ask how to connect Arduino to internet, so it can interact getting data from the internet and actuating physically. Let's say, turning a light on/off, open/close a garage door, turning the coffee maker on. :)

To do this, we could use an EthernetShield, giving the "power" to Arduino access the internet. Or we can leave this power to a PC, which already have it, and then the PC, through the USB, will send the info to the…

Arduino ARMed

 



This year 2 new Arduinos will arrive. Arduino Leonardo, based on a ATMEGA32U4 chip, which would be a low cost platform, with built-in USB and the promising Arduino Due. The Due will have a powerful ARM processor, that will remove most of the limitations from the standard version. From the press release:



"* Arduino Leonardo. Based on the Atmel ATmega32U4, it is a low-cost Arduino board which includes a simpler…
