Bio: Hi, I have a big fascination with LEDs. I guess it's because sometimes an LED lighting up is all that is needed to know that your circuit is working! I seriously became interested in electronics when I got the chance to build a LED display on a bicycle wheel in my Electronics Laboratory (PHYS 319) class at The University of British Columbia. Ever since then I always have some electronic project going on, just for fun! And they most definitely have LEDs. My hobby projects include a propeller clock and a speaker system with LEDs flashing to music. When working on my projects, I get a lot of help from others who have done similar projects and shared their experiences online. So I decided to document my projects in this blog: https://kasunsomaratne.com/ in case it will help and inspire someone else.
