MEET HI-FIVER-P. Our finger-counting LEDs kit is based on 10 bit counter. Using the push button switch as a clock generator consequently increases the 10 bit counter by one, therefore lighting the next LED. Since we wire pin 5 to the counter RST (reset) pin (pin 15), when the counter reaches the fifth position it automatically goes back to the first position when next button is pressed. i.e. lights the first-finger LED...
We use a NPN transistor, together with an RC circuit, to de-bounce the push button switch. This basic kit can work with many conventional NPN transistors i.e. 2N3904, 2N4401, 2N2222, etc.
RLX resistor determines the 5 LEDs brightness and limits the current flow to about 10 to 15mA when running between 9V to 12 VDC.
The HI-FIVER flash running rate is determined by the push button press rate.
