- UP / DOWN COUNT SWITCH
- RESET SWITCH
- PAUSE SWITCH
* 2 NAND logic gates (clock / oscillator)
* 1 Capacitor + 1 Resistor for clock speed
[Current settings: 100nF + 1KΩ =±3.5 kHz]
* 7 AND-logic gates to skip HEX 0A-0F
& to make 'up' pulse [ten / hundred digits]
* 2 NPN Transistors for boost 'up' pulse
* Slow simulation (many nodes) ¯\_(ツ)_/¯
Thanks for watching
