Level 1:
Control an output
Level 2:
Add an input
  • use a sensor (potentiometer, light sensor, microphone, ultrasonic sensor) to control…
    • the tempo of the LEDs
    • the timing of the servo
    • the pitch of the speaker
Level 3:
Add multiple functions
  • add a push button (or another sensor) to toggle the behavior of your circuit:
    • strobe vs glow mode
    • full servo spin vs partial spin
    • one melody vs another
Level 4:
Advanced circuits
  • add an advanced component (screen, Ethernet shield)
  • use more than 3 input/output components in a single circuit
Next level:
Design a new project
