WAB Robotics: Robotic Challenges 2025

When Roxie is not busy helping customers find their way throughout the store, she is using her user interface abilities to advertise different products.

Use the lights and tones to make a display or animated billboard for everyone to see! Use the SPIKE Prime hub to make an animated display or quick song.

Morse Code Headlight Challenge: Spell "HI"
Your task is to program the SPIKE Prime motion sensor headlights to blink the word "HI" in Morse code.

Morse Code for "HI":
H = .... (four dots)

I = .. (two dots)

Bonus Tips:
Use a function to blink a dot to avoid repeating code.

Use timing commands to control how long the headlights stay on and off.

Try adding more letters once you get comfortable!
