What's Arduino?
http://www.arduino.cc
Arduino•14 Digital I/O (6 PWM)•6 Analog In•16kb Flash Memory
•2kb for boot loader•16MHz Clock Speed•Serial Communication•USB Powered (or AC)•I2C
Arduino haz Flavor?

Arduino IDE
RAD IDE
Ruby + Physical Computing
•Control an Arduino with Ruby•RubyToC•AVR-GCC
•Most of the Arduino API ported to Ruby•Additional libraries
•Serial communications•Servos
Arduino Codeint ledPin = 13; void setup() { pinMode(ledPin, OUTPUT); } void loop() { digitalWrite(ledPin, HIGH); delay(1000); digitalWrite(ledPin, LOW); delay(1000); }
RAD Codeclass HelloWorld < ArduinoSketch output_pin 7, :as => :led def loop blink led, 1000 end end
RAD Methods•input_pin(s)•output_pin(s)•digitalWrite| digitalRead•analogWrite | analogRead•serial_print | serial_read•Keeping it simple
•It's all about the hardware
Coming Soon•Testing•Arduino Simulator•Better RubyToC Support•More "Out of the Box Support"
•LCD's•OLED Displays•Motors
