Coffee Maker Arduino

Have you ever wished you didn't have to make you're own coffee? When you get up in the morning, don't you wish the coffee maker would make coffee its self? Well now you can make that happen.

With this simple project, you can turn you're boring old Coffee maker into an automatic one.

Using a light sensor, we will be commanding our Coffee maker to make us Coffee as soon as it senses day light.

All you need is a few supplies, a coffee maker, and some wiring.

Supplies

For this project you will need the following items:

-Screw Driver

- Coffee Maker

- Alligator clips

- Hot Glue gun

For setting up you're circuit you will need:

- Breadboard
- Arduino

- Relay

- 1k Resistor

- Photo Sensor

- 13 wires

Step 1: Take Apart Coffee Maker

First we will need to connect the Coffee Maker to the Arduino. To be able to do that we also need to take apart the Coffee maker and expose its breadboard. This can be done with a basic screwdriver. Uncrew certain parts of youre coffee maker so that you have access to its breadboard

Step 2: Set Up the Circuit

We will be using a photo sensor to be able to turn on the Coffee Maker using light values. Set up the circuit using the picture attached to this document. Make sure to include a relay, and 100r resistor.

Step 3: Connect Arduino to Coffee Maker

To be able to control the coffee Maker using Arduino, we will need to connect our wires to the coffee Makers power circuit. Find the pin on the breadboard that has power on it, and connect you’re wire to it so then we can control it turning on and off.

Step 4: Reasemble the Coffee Maker

After the whole process of taking apart and wiring the coffee maker, you will need to make it neat and put back together. We had some trouble getting to the breadboard so we decided to superglue parts of the exterior that we had broken off.

Step 5: Finished Product: Code:

int lightpin = A0; //this is the pin that the photo resistor reads

int lightvalue;

int threshold = 700;//if the photo resistor reads this value it will turn on the coffee maker

int CM = 13;//this is the pin for the relay

void setup()

// put your setup code here, to run once:

{ Serial.begin(9600);//tells the serial moniter what frequency to read it at
}

void loop()
// put your main code here, to run repeatedly:

{
lightvalue = analogRead(lightpin);//this reads the photo resistor

if (lightvalue>threshold)//this means that if the light value is higher than the threshhold then it will turn on the coffee maker

digitalWrite(CM, HIGH);//this turns on the relay
else

digitalWrite(CM, LOW);//this turns off the relay

Serial.println(lightvalue);//this prints the photo resistor value to the serial monotor

delay(1);//this delays it one milisecond
