SHED-Article2SOFTWARE - Automation Example



(Copy the text in the box below and Paste it into a blank Arduino IDE window)</span>

/* SHED Magazine Arduino Sketch: Automation Example:
 This shows a way of organizing more complex automation software.
 It works the same as "Lighting Control Example"
 - Reads voltage on Analog Pin 0 and may display value
 - Reads voltage on Analog Pin 1 and may display value
 - Compares values and turns on light if it's darker than setting
 - SEE the comments after "//" on each line below
 - CONNECTIONS:
 - Potentiometer from +5 to Ground, center to pin A0
 - Photoresistor from +5V to pin A1, 10K from A1 to Gnd.
 - Relay may be connected to Pin 13 (or other if "ledPin" is changed.)
 - V1.03 09/23/12
