// This sketch is a good place to start if you're just getting started with
|
|
// Pixy and Arduino. This program simply prints the detected object blocks
|
|
// (including color codes) through the serial console. It uses the Arduino's
|
|
// ICSP port. For more information go here:

// It prints the detected blocks once per second because printing all of the
|
|
// blocks for all 50 frames per second would overwhelm the Arduino's serial port.
