First, I would like to thank all the Frontliners who are risking their lives everyday and I hope you guys are all doing OK [Yes, you too] despite the pandemic.
Welcome to Part 2 of the Bike Turn Signal Project Series.
This video would mostly consist small code changes and power draw tests.
I received the new pair of WS2812B matrices as replacement for the broken ones a few days before making the video.
I initially tried to use delays for the "blink" effect and opted to use FastLED's EVERY_N_MILLISECONDS instead.
On this project, I would still use the same ArduinoNANO, 8x8 RGB LED Matrix and PS2 Joystick Module.
I would also use my DIY Powerbank for the power source.
