The document discusses using Arduino to control LED lights and sensors. It provides instructions on the materials needed, example code snippets to make lights blink and change colors, and how to use a light sensor and serial communication with Processing. Examples include blinking an LED, alternating two LEDs, fading an RGB LED, and controlling an LED based on light sensor input read over serial. Links are provided for downloading Arduino software and references.

15. Uporniki - moč in računanje upora
Upornik se upira električnemu toku in mu
preprečuje, da bi nemoteno tekel skozenj.
Napetost (V) = Tok(I) * Upor(R)
Upor: 220 Ohmov
Napetost: 5 Voltov
====================
Tok: 23 mA (mili amperov)
5V = 23 mA * 220 Oh
5V = 0.0227A * 220 Oh
