- What is the RGB LED strip?
- Digital RGB LED strip.
Circuitry - 5 minutes
- Connect RGB LED strip to evive
Blocks - 10 minutes
PictoBlox Lighting Extension blocks to control the individual RGB LED:
- Initialise RGB strip () with () LED pixels on pin () block
- Set RGB strip () LED pixel () color () block
- Show RGB strip ()
Activity 1 - 15 minutes
- Make a script to give a different color each LED.
Activity 2 - 20 minutes
