Project
Open hardware
• Open hardware
– Inspired on the free software? not, open software
– It’s not a new concept, first open hardware: early
70s (XX century)
• Definitions
– Hardware device whose specifications
and schematics can be accessed publically (free or
not free charges)
• Open Hardware Specification Program
– Limited form of free hardware.
– Enough information that allows a
programmer to make a driver.

Arduino background
• Origin of Name
– Its name comes from "Bar di Re
Arduino" where Massimo Banzi
spent a few hours (is the name of
an ancient European king (year
1002)

– Massimo Banzi
• Motivations
– In 2005, a group of students, and
professors of the Institute of
Interactive Design of (Ivrea) in
Italy started to develop a
Hardware platform because
commercial platforms are
expensive and closed systems.
– Made entirely in Italy
– Target: price < 30 €
– Philosophy: DIY (Do It Yourself)8

• Processing is similar al C, but it is possible to
program Arduino in other languages
• Aimed at users who do not need to know high
level languages
• Oriented to programmers unfamiliar with the
hardware.
• Conditions GNU LGPL

– #4 Interchange polarity between Vin y GND
– #5 Short circuit Vin y GND
– #6 Apply voltage to output voltage pins (5V y 3V3)
– #7 Apply more than 12 V to reset pin de reset
– #8 Over charge the Arduino (connect to Arduino a
great amount of components without additional

– Review connections before connect the Arduino
– No force conectors
– In case of failure: Test every component
individually
– Do not desperate: it is difficult for a run at the
first assembly
• Software
– Save code frequently
– Comment the code
– One change… one test
