LED Fun

Snap Circuits® uses electronic blocks that snap onto a base grid to build different circuits. These blocks have different colors and numbers on them so that you can easily identify them. Build the circuit shown by placing all the parts with a black 1 next to them on the clear base grid first. Then, assemble parts marked with a 2. Install two (2) “AA” batteries (not included) into each of the battery holders (B1). Lay the mounting base on any LED (D1, D6, D8, or D9) and place the fiber optic tree in it.

Turn on the slide switch (S1). Move the lever on the adjustable resistor (RV2) around to change the brightness of the LEDs. The blue & color LEDs will be blinking. For best effects, place the circuit in a dimly lit room. Also, try swapping the the LEDs with each other.
