dan-mckay / AnalogInOutSerialThreeLED
Created Nov 1, 2012
Takes a potentiometer reading and controls dimness of 3 LEDs
View AnalogInOutSerialThreeLED
// These constants won't change. They're used to give names
// to the pins used:
const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
const int greenOutPin = 9; // Analog output pin that the green LED is attached to
const int yellowOutPin = 10; // Analog output pin that the ylw LED is attached to
const int redOutPin = 11; // Analog output pin that the red LED is attached to
int sensorValue = 0; // value read from the pot
int outputValue = 0; // value output to the PWM (analog out)

dan-mckay / servocosm.js
Created Apr 16, 2013
This code queries the Cosm API for a reading from a remote sensor. This reading is used to manipulate a servo motor that is connected to an Arduino on the host machine. It is a Node.js application that uses the johnny-five module.
