When working on 20×4 (or bigger) lcds font dimension can become an interesting issue: [liudr] shared & updated its Phi_Big_Font library The Phi_big_font library utilizes 3 X 5 dot matrix technique I developed to display characters 6 times the size of ordinary characters seen on HD44780-compatible character LCDs. You will need two rows and 4 […]
As seen in the streaming of Google IO 2011, physical computing and interactive enviroments are one of the main topics opening the conference. The Android Open Accessory Kit is going to allow Android related devices receive data from different sensors (just via USB, for now). The Android Open Accessory Development Kit (ADK) provides an implementation […]
Nice RESTduino demo #1 by [Jason Gullickson]: what is RESTduino? RESTduino is a simple sketch to provide a REST-like interface to the Arduino via the Ethernet Shield. The idea is to allow developers familiar with interacting with REST services with a way to control physical devices using the Arduino (without having to write any Arduino […]
As [Kalanda] published on its blog (spanish) and github, there is one more (easier) way to establish connection with an Arduino over a network connection (among the others): serial2socket-proxy is a cross-platform software application developed in Processing for creating a virtual connection between the serial port and a network socket port. For example, you can […]
Last week I was in Rome for the Arduino Day. I was amazed by the projects and the people there: true Arduino fans. This is the first post about some of those projects: more soon. [anbello] generates – via MIDI – different light patterns on a strip of addressable RGB LED MIDI messages from the […]
Japan’s difficoult moment has challenged many Arduino users (I can count at least three different threads on the forum about geiger tube & sensors lately 1, 2, 3). As David posted some time ago, the need of an open, net-spreaded visualization of the real level of radioactivity was heavily felt by the community, also for […]
Some time ago [ant.b] from the Arduino Forum manage to reflash the Atmega8u with other LUFA Firmwares. [Dimitri Diakopoulos] has recently developed a similar approach for his HIDUINO project. Very good explanation & references. Diakopoulos succeded to make Arduino show up as a MIDI Device: LUFA powers the HIDUINO project in that it handles most […]
[pabloxid] shared an Hexapod project on the forum based on an Arduino MEGA 1280 and 18 Dynamixel AX-12 motors: SAMSA is based on the Wiring board, with an ATmega128 microcontroller, and SAMSA II on the Arduino Mega, with an ATmega1280. Both are pretty similar, tough the ATmega1280 has 8 KB SRAM, twice the ATmega128. For […]
[Michael] posted some interesting uses of Nootropic’s latest shield, the Video Experimenter Shield, besed on a LM1881 video sync separator to detect the timing of the vertical and horizontal sync in a composite video signal. It’s one of the few examples of Arduino processing a live video signal, as previously seen with the Eye Shield […]
[Jeremy] made ten Tutorials about Arduino worth our “All Stars” category. He talks about different themes: Blinking Leds [Intro & #2], Electrical Engineering [#3], Analog Inputs [#4], Motors & Transistors [#5], Serial Communication & Processing [#6], I2C & Processing [#7], SPI Interfaces [#8], Wireless Communication [#9] and Interrupts [#10]. Thanks to a generous sponsorship from […]
