Hello guys !
First of all , sorry for this maybe stupid post but I really need some help ...
I am currently working on a LED based clock, but i want to build it oldschool so no adruino, raspberry pi oder other "advanced" devices, just a quartz crystall signal tht will be transformed into a 1Hz signal,
some (probably about 18 of them
) Shift registers (8-Bit) of the type "74HC595" and the LEDs...
But here comes my problem - the shift register has by far not enough power to supply an LED so what I need are transistors - there comes my next problem - which ones should I use for tht job ? I will be using about 140 LEDs to show the time so Id prefer some kind of IC tht is packed with ~10+ Transistors for this use.
If it matters how tht clock will work, ill post it in another post right here .
So already a BIG "thanks" to all the ppl tht are willing to help me out !
(I am not a native speaker so please excuse my mistakes)
