Timeline

Week 1- Week 4- Lecture notes

Week 5-  First Group Meeting:

1) Planned to meet every Wednesday 5 pm-8 pm, thereafter.
2) Developed Schematic voltage divider
3)Budget ($60.00)

Week 6- we worked on the circuit by the items that were  provided by our Class TA
Items provided:
Breadboard
Wires
Resistors
Arduino kit
LED's

Ordered from DigiKey (Total $15.72)
Thermistor
Photo Resistor



Week 7- Building greenhouse

List of the items from Home Depot:

1" x 12" x 6' ($16.50)
Dimmer 120V ($12.95)
Light bulbs ($5.00)
Thermometer ($5.00)

Items already had: 

11.5 x 11.5 Poly-carbonate
Screws 1&5/8" (Drywall screws)
Hair Dryer
Light Fixture
Extension wire 22Ga

Scale down green house was built out of 1"x 12" (.75" x 11.50" nominal) pine and .75" poly-carbonate
The 1" x 12" was cut down for 5 of the 6 sides
The bottom - 11.50" x 13"
The back - 11.50" x 11.50"
Two sides - 11.50" x 11.50"
Top - 11.50" x 12.25"
Front (.75" Poly-carbonate) 11.75" x 11.75"  (it was pre-cut at a glass shop)

The green house is secured together by 1.625 drywall screws.
A 2.5 inch hole was drilled in the side for a port to add heat
A 1.5" hole was drilled in the top piece to allow a light to be mounted through
2 - 1/4" holes were drilled in the side near the base to pass wires through



and so far...

Week 8- Today we were testing and updating our circuit board, sketch of the green house using CREO and hand-sketches.
We plan on spending most of our time this week on coding to control the Arduino which is an open-source electronic prototype platform. By coding we should be able to control overall lighting by turning the Lights ON/OFF based on the natural light input and current temperature of the green.
The code so far is:

//declaring inputs and outputs

int sensorLightValue=0;

int sensorHeatValue=0;

int sensorLightPin=A0;

int sensorHeatPin=A2;

 int LED1= 13;

 int LED2= 14;

 int LED3= 15;

void setup() {

Serial.begin(9600);

  //declares the LED's as an output:

 pinMode(LED1, OUTPUT);

 //pinMode(LED2, OUTPUT);

 //pinMode(LED3, OUTPUT);

}

void loop() {

 //reads the values from sensors:

sensorLightValue= analogRead(sensorLightPin);

Serial.println(sensorLightValue);

sensorHeatValue= analogRead(sensorHeatPin);

 Serial.println(sensorHeatValue);

 delay(1000);

 //turning on LED's

if (sensorLightValue > 250) digitalWrite(LED1, HIGH);

if (sensorHeatValue >50)   digitalWrite(LED2,HIGH);

if (sensorLightValue >100) digitalWrite(LED3, HIGH);

if(sensorLightValue <250) digitalWrite(LED1,LOW);

//wait for sensorlightvalue seconds long

//delay(sensorLightValue);

//turn off sensors

//digitalWrite(LED1,LOW);

//digitalWrite(LED2,LOW);

//digitalWrite(LED3,LOW);

}
