Beginner Projects

  1. LED Blinking Traffic Light

    • Description: Build a simple traffic light simulation with red, yellow, and green LEDs that cycle in sequence.
    • Learning Objectives: Digital output, basic timing with delay(), and code structure (setup/loop).
    • Components: 3 LEDs, resistors, breadboard, jumper wires.
    • Suggested Board: Arduino UNO R4 Minima.
    • Code Concept: Use digitalWrite() to turn LEDs on/off with timed delays.
    • Challenge: Build a second traffic light that interacts with teh first and emulates a real crossing.

  2. Button-Controlled Buzzer

    • Description: Press a button to make a buzzer play a tone; press again to stop it.
    • Optional: add a led that shows when te buzzer is playing.
    • Learning Objectives: Digital input, conditional statements (if), basic sound generation.
    • Components: Pushbutton, buzzer, resistor, breadboard.
    • Suggested Board: Arduino Nano Every.
    • Code Concept: Read button state with digitalRead() and use tone() for sound.

  3. Temperature Monitor with LCD

    • Description: Display room temperature on an LCD screen using a temperature sensor.
    • Learning Objectives: Analog input, sensor interfacing, LCD output.
    • Components: TMP36 or DHT11 sensor, 16x2 LCD, breadboard.
    • Suggested Board: Arduino UNO R4 Minima.
    • Challenge: add a led and/or buzzer that switches on when the temperature is outside of a preset range.
