Product details
By means of a random generator, a random LED lights up after a button press and a short voltage phase. Everyone can guess beforehand which color will appear or which LED will light up in the end. Thus, the "electronic roulette" kit also serves as a simple version of roulette. Thanks to the detailed colored instructions and the included bending aid for resistors and diodes, the soldering kit "electronic roulette" is excellent for beginners, newcomers, and advanced users. A standard 9V battery (not included) is used as the power supply. This soldering kit controls two red 5 mm LEDs to blink alternately. The blinking speed can be individually adjusted for each LED. The "blinking LEDs" circuit board is great for experimenting, as a soldering practice, or for light functions in model building, such as a level crossing signal.
