ARPainting: Draw on AR Canvas
This was the first AR project I made in 2016. You draw on the AR canvas on your phone, and on the other side, the LED matrix will display the character you draw.
The Tech Stack
The hardware part contains an Arduino board and a ESP8266 module. The software part is the combination of Unity + Vuforia + Arduino IDE + Flask (Python server) + Tesseract OCR.
