Fritzing and Arduino Code

The following is the final code for our project and the wiring.

#include <Servo.h>

Servo myservo;

int val;

void setup()

{

  Serial.begin(9600);

  myservo.attach(12);

  myservo.write(120);

}

void loop()

{

  Serial.println(analogRead(0));

  val = analogRead(0);

  

  if(val > 500)

  {

  myservo.write(60);

  delay(5000);

  myservo.write(120);

  while(1) { }

  }

  delay(1500);

}

Presenting the Project

Although we ran into a problem with our relay and the coffee maker was not 100% working, we presented the final product at UCrossing today. Many people were interested in our coffee maker and wanted to know how it worked. Overall, the presentation went very well and we got to see a lot of other group's projects as well.

Finalizing the Project

We ran into some major speed bumps in creating the project, but it's done. It took a while to create all the parts, but we got them and assembled the support beams and the plates onto the coffee machine.

The coding ended up having too many problems and began consuming too much time. In order to complete the project on time it had to be altered slightly. Instead of being activated through a text message, it is now activated using a photo resistor. When there is enough light, the coffee machine will be turned on. This way when you turn the lights on in the morning, your coffee will begin brewing.

Parts Made

After running into a few problems and waiting in line for over an hour, we got our laser cut parts made. Due to problems with the 3D printer, we could not get our part printed. So we had to redesign the water reservoir door so it could be laser cut.

Problems with Coding

Brendan and Alex sat down today to try and finish the coding for the Raspberry Pi and the Arduino. Without getting too technical we're having trouble getting the Raspberry Pi to read the text message and send an output message to the user. This is a major setback and is going to hold back the whole project if it can't be solved.

We're going to try to see if they can solve the problem tomorrow, but if we can't we may have to resort to Twitter controlling the Raspberry Pi. This would be a bit easier as most of this code has already been written and is known to be functional. It's not ideal, but at least it will work.

Brendan also wrote most of the Arduino code that will receive the code from the Pi and output power. All that's left is to write the code for the motors.

Coding is Almost Done

The Electrical Team worked on the code a little bit today. They've adapted some code taken from this source. This code is written for the Raspberry Pi that will automatically check a Google Voice inbox for messages.

Alex and Brendan have made some changes to the code so that it will check the inbox and output a serial to the Arduino. It still needs some work, but progress has been made.

Hours Worked:

Alex- 1 hour

Pieces coming together

In today's group meeting Corey and Billy made the water reservoir with the supplies bought yesterday and finalized the Solidworks part that must be laser cut and another that will be 3D printed.

Supply Shopping

Yesterday, the group went to Lowes to buy materials for the project. We bought PVC piping, silicone caulk and various others to retain the water before it is loaded into the coffee maker.

Design Stage

Today the mechanical team, William Jacobson and Corey Garrigan, used SolidWorks to model the automatic coffee machine assembly. Measurements were taken of our coffee maker and a model of the same scale was created  in SolidWorks. With a 3D model made, we will easily be able to edit our designs and parts from our laptops.

Next, we started to design the parts that will load the water into the coffee maker. We've decided to go a cylinder to hold the water and the bottom panel (of the cylinder) will be able to slide out, allowing water to flow from the cylinder and onto a track that goes into the coffee maker. The stepper motor included in the arduino kit will be used to move the bottom panel.

We've also come to the conclusion that the bottom panel will need to be 3D printed. So, our design of that specific part needs to be finalized soon and sent in for printing if we want it in time.

Beginning Work on the Project

After figuring out our project idea we decided to get working on it today. We decided to split our team into two groups based off our knowledge and start planning out the machine.

The electrical team consists of Brendan Ford and Alex Cushing. Together they were able to load the Raspberry Pi with the proper Linux OS and get it configured correctly. They also did some research on other people who had done similar projects and were able to get enough resources together that they feel comfortable putting together some code.

The mechanical team consists of William Jacobson and Corey Garrigan. They began drafting ideas for the loading of water and coffee grounds into the machine. They also began tinkering with the various motors and the Arduino Board.

Significant progress was made today and we feel much better about our plans for the machine.
