Hey people

disclaimer!

this project makes use of voltages higher than 12 volt and can be deadly if not done correctly.

we do not take any responsible for any accidents that may happend during the making of this machine.

if you are gonna attempt to build this machine always consult an expert.

Today where gonna show you how to make a alarm clock turn on your coffee machine using an arduino!

The things you will need are:

  1. - arduino
  2. - relais
  3. - alarm clock with speaker
  4. - simple coffee machine
  5. - wires
  6. - breadbord
  7. - 2x an screw teminal
  8. - 8x ferrule

tools:

  1. -soldering iron
  2. -mulimeter
  3. -crimper
  4. -screwdrivers

Step 1: The Alarm Clock

break open your alarm clock, and solder 2 wires to the positive and negative wires that are connected with the speaker.

Step 2: Connect the Relais to the Arduino

connect the relais to your arduino

as shown in the picture.

Step 3: The Coffee Machine

1. prepare the cables.

you will need 2 long cables

attach the ferrules to both sides of a long cable.

2. cut the brown wire in the coffee machine and connect it screw terminal.

do this with both of your wires

Step 4: Connect the Cables With the Relais

like shown in the picture

Step 5: Arduino Code:

const int wekker = A0;

const int koffie = 2; const int aantalminuten = 1;

void setup() { // put your setup code here, to run once: Serial.begin(9200); pinMode(wekker, INPUT); pinMode(koffie, OUTPUT); }

void loop() {

// put your main code here, to run repeatedly:

int alarm = LOW;

//Serial.println(aantalminuten);

alarm = analogRead(wekker);

Serial.println(alarm); delay(100);

digitalWrite(koffie, alarm ); if (alarm >= HIGH){ delay(60000 * aantalminuten); }

}

Tips

Cool project! If your arduino can connect to internet, you don't even need the alarm clock. You can use an app like Blynk to have your output koffie turn on at a given time. every morning.

Wat grappig, ik ben serieus ook op dit moment bezig met een koffiezetapparaatwekker, precies dezelfde manier ook

I miss having a coffee machine on a timer! Great setup :)
