Random number generator for more realistic effects
Power supply: 9-12VDC max or 9V battery (sold separately)
The Snowman Welding Kit has 69 multi-color LEDs. No need to remove the battery when using an external power supply, it runs on 12V and comes with an on/off switch.
PWM controlled LEDs create a beautiful snowflake effect. Use a random number generator for a more realistic effect.
