Skateboard with PIC microcontroller and LEDs
What do you get when an Electrical Engineer builds a Skateboard from scratch for a 13 year old’s Christmas present? You get a skateboard with eight white LEDs (headlights), eight red LEDs (tailights) all controlled via PIC microntroller! And I might add, one very happy 13 year old, well as happy as a 13 year
