This week I finalized the design for LED grid and worked on hardware integration. The LED strips only work with 2 of the pins on Jetson Nano (SPI MISO, apparently not all GPIO pins are equivalent), so I ended up soldering a LED grid from individual LEDs from scratch. It was a lot of designing, wiring and soldering involved. (There are 2 grids lighting up in the photo below.)
I moved our design into a mini fridge for final demo and spend a lot more time soldering and wiring. The camera and microphone is mounted. The code is also ready to be integrated.
I will do some integration test tomorrow, and help Elena prepare the final presentation slides.
