Section 13 Comprehensive Projects

This section showcases several comprehensive projects created using Arduino programming. Through these projects, you can apply the knowledge points learned from previous chapters to practical applications.

  • Traffic Light: Controls multiple LEDs to simulate the sequential logic of a traffic signal.
  • SOS: Controls a buzzer and an LED to emit the SOS Morse code signal.
  • Motion Sensor Light: Uses a PIR sensor to detect human motion and controls a WS2812 LED strip.
  • LED Strip: Uses a potentiometer to control the color-changing effects of a WS2812 LED strip in real-time.
  • Progress Bar: Uses a potentiometer to control the progress bar and gauge displayed on an OLED screen in real-time.
  • Weather Display: Connects to the Seniverse Weather API via Wi-Fi to obtain real-time weather data and displays it on an OLED screen.
