How It Works

The flashing light circuit is built around a multivibrator formed by three transistors (triodes), making it a highly reliable and educational circuit design. During assembly, be sure to observe correct LED polarity and transistor insertion direction. Leave approximately 6 mm of pin length after insertion and bend the pins parallel to the board before soldering. Take care not to overheat the LEDs during soldering. Boards 30A and 30B must be cross-inserted correctly before mounting onto the base plate — double-check power polarity markings before final soldering.
