Next is the complete schematic diagram of a little Arduino board for your everyday projects. Use the Atmega328P chip, with Arduino bootloader loaded by you, as the brain of this economical circuit.

An Arduino is by no means expensive, but that still doesn't mean that it suits your needs right out of the box. If you want to make your own custom board, Make shows you how in a three-part series.

Prototype was constructed & tested using “Arduino UNO-R3” board; Sketch created,compiled & uploaded (to Arduino board) using Arduino IDE0022; Piezo-Speaker in the circuit is a “passive piezo-speaker”.

If you’ve been reading this blog for a while, you’ve probably seen us refer to the Arduino microcontroller on a number of occasions. This little circuit board is at the heart of many DIY ...

It’s based on an Arduino Due, and uses some custom I²C multiplexer boards to wrangle all the various inputs. We love the look of this panel, especially the appropriately Futura-fonted labels ...

Intel just announced at Maker Faire Rome that the first product to use the Curie module is a brand new, low-cost Arduino board called Arduino 101.
