Beskrivelse
Stop scrolling! Og ta deg tid til å sette pris på enkelheten og elegansen til en lys hvit LED, som så altfor ofte blir oversett ved siden av sine oppsiktsvekkende RGB-venner. Pico Scroll Pack inneholder 119 hvite lysdioder i en fin 17 × 7 matrise. I tillegg får du her fire taktile knapper for å samhandle med Pico. OK, du kan begynne å scrolle igjen.
Lysstyrken på hver LED kan naturligvis kontrolleres individuelt, og gjør denne derfor veldig hendig til visning av grafer, rullebeskjeder, beroligende snøanimasjoner eller lignende. Se under for nøyaktige funksjoner og bruksanvisning.

Pinout
Pico Scroll Pack talks to the IS31FL3731 LED driver chip over I2C requiring only SDA and SCL pins.
The four switches are wired up as SW_A, SW_B, SW_X, and SW_Y.
Power is supplied through VSYS meaning that you can use Pico Scroll Pack both on USB power and from external supplies (so long as they can supply 3V+) making it ideal for battery powered projects.
This leaves the majority of pins on your Pico free for other uses!
