I was doing research in brain-computer interface and was interested in the technique of transfer learning. Based on numerous papers I read, KL-divergence is a common method to measure similarity of distribution between subjects’ EEG signals. At that time, I found an article that explained KL divergence to measure similarity…

We need to create a program (code) to deliver our instructions to MCU. For this AVR-based microcontrollers, the language we are using is called Embedded-C, which is basically the extension of C language, so if you have basic in C, that’s a plus. There is something so basic yet important…

Microcontrollers are amazing, it runs on almost all home appliances. They run your phone, play the music, clean your t-shirts, warm your meal, and show your favorite movie. Before getting into those complicated features, it’s reasonable to understand the fundamental of programming microcontroller. Based on my own understanding and setup…
