✅ analogWrite range → 0 ~ 255

Lab 3) Sensor Change Detection

• Three common changes in sensor readings that give information about events in the physical world →use it when we design to read user’s actions

  • state change detection on digital sensors
  • threshold crossing
  • peak detection on analog sensors

• Digital Sensor vs Analog Sensor

  • Serial Plotter(Arduino Tools menu, command+shift+L)
