Coffi

My name is Werbrouck Flor and just like everybody in the ICT-Sector I am addicted to coffee. So when I got the challenge from my school Howest to make a project at the end of my first year, I wanted to make a device that would make coffee for me when I would wake up. That's when I decided to make Coffi.

Electronics:

• Raspberry pi 4 + GPIO breakout
• SD card
• I2C LCD screen
• Light Dependent Resistor
• Ultrasonic Sensor
• LED strip
• One-wire temperature sensor
• 5V relais
• Level shifter
• Industrial power supply

Materials:

• Cardboard box
• Wires
• Glue

Download the raspberry pi image from their website, Once you've written the image onto the SD-card, you will need to put the raspberry pi on wifi. Boot up the pi and install the Requirements.

Use "sudo raspi-config" to open the PCF, SPI and One-wire in the Interface Options.

Now we can make a connection to the database over wifi and insert our database.

Connect all the electronics to the Raspberry Pi, we can use the 220V from the cable of out coffee machine to get 5V for the raspberry Pi.

With MySQL workbench you can set up an ssh connection with your database, run Coffi.sql in MySQL workbench

You can find the code here.

I use visual studio code to edit the program because it has an "SSH" plugin.

When you run the program and then go to IP-Address it says on the LCD screen in your browser you should be able to plan a coffee & etc...

I've put everything of the electronics in a cardboard box so it looks a lot cleaner.
