Arduino and Freeduino Knowledge

Things are easier than before, there is so much more you can do with this. Starting with a Embedded Project with Arduino type of uC is easy. A PC USB inteface for testing your code. Analog Interface is good for trying out Measurement or Robotic Projects.

Freeduino began as a collaborative project to publish open-source Arduino-compatible production files. The files that resulted from this project allow users to create boards that are 100% functionally, electrically and physically compatible with Arduino hardware. Over time, Freeduino has come to mean hardware that is "Arduino-compatible".

Arduino and Freeduino Knowledge

Arduino and Freeduino Knowledge

Freeduino is a free-form version of the Arduino, in that is not developed under a centralized design process.There is no Freeduino team, or anyone to ask permission of: anyone, anywhere, can design and produce a Freeduino product, no questions asked, no royalties paid.

It's sort of like electronic harware anarchy- or democracy, depending on how you look at it. We derived the Freeduino files from Arduino for exactly this reason: to see what the Arduino project would have looked like if it had open hardware distribution and manufacturing.

Arduino and Ethernet Interface

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

Arduino Open-source Electronics Prototyping

Arduino Open-source Electronics Prototyping

The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

Arduino Ethernet

Arduino Ethernet

The Ethernet differs from other boards in that it does not have an onboard USB-to-serial driver chip, but has a Wiznet Ethernet interface. This is the same interface found on the Ethernet shield.

The Arduino Ethernet is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, a RJ45 connection, a power jack, an ICSP header, and a reset button.

Transistor-Based Variable Current Drive for LED Calculator

"The idea is to expand on a simple LED tester by allowing the user to plug in an LED, dial in the LED brightness, and then read information on an LCD showing the LED voltage drop, the current current, and the value of current-limiting resistor to use in a target circuit. "

NYC Resistor - Hack Build Learn DIY Electronics

NYC Resistor is a hacker collective with a shared space located in downtown Brooklyn. The NYC Resistor Microcontroller Mailing List is a great place to meet others with the same interest...

NYC Resistor - Hack Build Learn DIY Electronics

"In this hands-on workshop, you'll learn how to use a soldering iron safely and effectively, and get plenty of practice with both soldering and desoldering techniques. We'll be soldering up some Game of Life kits - LED tiles that generate nifty animations."

Intro to Soldering Workshop
