Adafruit Gemma M0 connected to LPD8806-48 LED strip with SPI port
The Adafruit Gemma M0 is a quarter-sized microcontroller board with a 48 MHz 32-bit Cortex M0+ processor, 256 KB flash, 32 KB RAM. Most importantly it's $10!
The Adafruit LPD8806x48 is a flexible weatherproof strip of digitally-addressed (individually-controlled) LEDs with 7-bit precision on red, green, and blue.
There's no library for connecting them together, so I wrote some code to use the Gemma M0 integrated SPI hardware bus.
Best Free Resources to Get Started With Robotic Perception
Robotic Perception is how robots estimate their environment with measurements. I've linked the best free resources I used to learn about perception below.
Maneuvering road object tracking with the IMM algorithm and an imaging radar sensor
This paper summarizes how an interacting multiple model (IMM) algorithm uses measurements from an imaging radar sensor to estimate the dynamic state of a maneuvering road object with unknown control inputs.
Written as a final project for the excellent AA273 class State Estimation and Filtering for Robotic Perception, part of the Stanford Robotics and Autonomous Systems program.
