Session 1 — Warm-Up and Review

Activity:

• Ball game (accessible to all, barcode-only)
• Returning students: quick EdBlocks refresh — open app, connect Edison, run a drive program
• New students: barcode exploration with returning students as mentors
• Class demonstration: line-following barcode vs. obstacle avoidance — what’s the difference between these sensors?

Materials: Ball game setup, barcode list, devices, USB cables
