Function: When power is on, 7 LEDs will randomly display multiple points. The player presses the switches S1 and 7 to light the LEDs. After about 7 seconds, the LEDs will start to flash until the stable point is displayed. The entire first “trial” process ends.
Circuit: The circuit is mainly composed of a pulse generator and a decimal counter circuit. The pulse generator and external components are made up of NE555 multivibrator. When you press S1, Q1 turns on, output pulse NE555 3 feet, then outputs CD4017 output high voltage. Different combinations of resistors and transistors can drive 7 LEDs to indicate the number of points. 1-6 points.
