By random generator, any LED lights up after a button press and a short voltage phase. Everyone can guess which colour appears or which LED lights up at the end. Thus, the "electronic wheel of fortune" kit is also suitable as a simple version of a roulette. Thanks to the detailed coloured instructions (English language not guaranteed) and the enclosed bending aid for resistors and diodes, the soldering kit "electronic wheel of fortune" is ideal for beginners, beginners and advanced users. A standard 9 V battery (not included) is used as a power supply. With this soldering kit, 2 red 5 mm LEDs are activated flashing and light up alternately. The flashing speed can be individually adjusted for each LED. The "flashing LEDs" board is great for experimentation, as a soldering exercise or e.g. for light functions in model making, such as St. Andrew's cross, etc.
