Základné programy

Blinker

Pre prácu so svetielkami na hornej hrane robota je potrebné nahrať knižnicu Neopixel

Jednoduchý program pre blinker, funguje na tlačítka - stlačením ľavého tlačidla 🅰 sa zapne ľavá smerovka, pravým tlačidlom 🅱 sa zapne pravá. Stlačením oboch 🅰+🅱 sa blinker vypne.

Základné pohyby

Výrobca, firma Kitronik poskytuje pre robota špeciálnu knižnicu. Niekedy sa volá iba Kitronik, ale väčšinou ju nájdete pod názvom Servo:Lite

Tento ukážkový program len pohýbe všetkými smermi a potom skončí.

Line following robot

Robot musí byť doplnený špeciálnym senzorom, ktorý sa pripojí k expanznej doske, umožňujúcej využiť aj viac ako 3 vstupy P0 - P3. Samozrejmosťou je tiež vopred nahrať knižnicu Kitronik
