Smart-Fridge

Hello everyone, we had to make a project for our first year in MCT at HoWest. I chose to build a Smart-Fridge and give it my own little touch! I tried to make it as 'cheap' as possible so everyone will be able to make it! In this instructable i will try to lead you through the whole project so you can make this Smart-Fridge all by yourselve! Enjoy!

Step 1: Tools and Materials

• Raspberry Pi 4
• Arduino Uno
• Distance sensor sr05
• LDR sensor
• 220 ohm resistor
• 4,7k resistor
• Jumper wire cables
• Ds18b20 temperature sensor
• Ethernet cable
• RFID-RC522
• Electrick lock
• Level shifter
• LCD display
• Saw
• Wood
• Glue
• 12v battery
• Soldering Iron

Step 2: Electronics Scheme

Here you can see how my electronic scheme is looking!

Step 3: Building the Project

Step 1: draw and measure

1. We will need 4 pieces in total! 1 to put the drinks on, 1 to stop the drinks from falling when you open the fridge! And 2 to give the plate a downangle so the drinks come to you automatically!
2. Measure the 4 pieces so they fit perfectly in your fridge! You will need a measurement tape for this job!
3. Draw the lines so you know exactly where you need to cut with your saw!

Step 2: Saw

1. Now that you drew everything it's time to put some 'dirty' work in! Take a saw and start cutting of all the pieces you don't need! I use a vice for this so that my shelf will be steady at all times when i try to saw it.

Step 3: Glue it!

1. Put everything together with a glue gun! Try to be as precise as possible so you're shelves are in the right place and you don't need to start all over again!

Step 4: Database

If you want to know how my database looks!

Step 5: Programming Code and Pi Setup

You always can write your own code! But if you want to make it easy for yourselve i will let my github repo in here so you just can use my code as an example!
