The goal of this project is to make a LED matrix/sign for displaying messages in the window. It's controlled by a Raspberry Pi and an ESP32.

The ESP32 will be responsible for sending data to the LED matrix using RMT or SPI depending on which one works best with many LEDs. It will also act as a TCP-server and receive the text you want to display in the window from the RPi. Connect to the RPi via ssh and run insert file name here with the text.

The plan is to make it 12 LEDs in height and about 100 LEDs in length, which roughly translate to 20 cm and 160 cm.

Python running on the RPi and C code using the Espress-if build system on the ESP32.

• Acquire a suitable power supply for all the LEDs (it's a lot!)
• More LED-strips
