Enjoy!

For the past 6 weeks, this Connectree was my baby. We had good times together, but sometimes there were also downfalls. Either way I am very proud of this project.

With this connectree, I want to reinvent the true meaning of a Christmas tree. How can a Christmas tree connect people and create warmth and happiness, how can I make a Christmas tree smart?

Sending data from the web to the Arduino: check. Sending dat from the Arduino to the web: check. Sending data from Arduino to Arduino:

On top of the problems with flash memory, I also have a problem with the maximum number of characters I can retrieve from the Firebase database.

I tried a few other things to free up more space on my Arduino board.

When I wanted to add animations to the led strips I ran into memory issues of the Arduino.

After 4 weeks of looking at a screen almost every day, it felt good to get outside and work with my hands.

A little more explanation of how I approached my planning during this assignment.

Cats can be cute, but no Christmas tree is safe from them. That's why I put a sensor in my Xmas tree 2.O that can detect if it's being attacked by a hostile cat.

How do I show vector based text on a pixel based led strip?

How do I show a drawing on a pixel based led strip?

So far I have put all my LED strip code on an old Arduino uno, and all the Wifi related code on a newer Arduino. I assumed that the library of the leds was also going to work on the new Arduino...

How can I control who can send messages to my tree? What is the most logical, user-friendly and secure way to do this?

How do I show vector based text on a pixel based led strip?

Over the past 4 days, I have soldered 120 wires together

Video of a first MVP. Sending a message from a browser to an Arduino (Browser <=> Firebase <=> Arduino)

Day 10 of trying to control my Arduino over a website. In this blog, I'll try to connect an Arduino Uno Wi-Fi Rev2 with a Firebase realtime database.

Day 9 of trying to control my Arduino over a website. In this blog, I'll try to control an Arduino Uno Wi-Fi Rev2 through a website

Day 7 of trying to control my Arduino over a website. In this blog, I'll try to control an Arduino Uno Wi-Fi Rev2 through a website

My led strips arrived in the mailbox. In this blog post I send basic code to the led strip to test it.

I tried out the cheapest option to equip my Arduino Uno with Wi-Fi. Spoiler alert: It didn't work.

What shape was my Christmas tree going to take? It didn't necessarily have to be a traditional conical shape, I went to several stores for inspiration.

I was doing research on how to control my Arduino through a website.

I have been researching different types of lights that I can hang in my tree.

A summary of my top 3 concept (and their feedback). Which one will make it?

I wanted to take my mind off the concept part and worked on a first demo with ardiuno. A technology I would like to learn more about.

Today I was washing my hands next to our teacher Koen in the buda toilet. We all know that the water taps have a sense of rhythm. Then Koen said to me while laughing "you could make an installation out of it". - Can I?

In this blog post I'll take you through my thoughts to a first few concepts

For the final expert development assignment, all paths are open. Where do I wanna go with this project? What technologies do I want to use? For whom shall I make this project?
