[SOLVED] How I Create 555 Timer For 30 LED

[nhawan429]

Hi Friends My Name Nazakat From Pakistan .
How I Make 30 Led project With 3 Led effect
and use 556 or 555 .plz help I am New in electronic Field.Thanks

dear. connect base of a bc107 or equal transistor to output of 555 with 100 0hm resistor, collector to Vcc and emitter should be grounded by loads. load should be parallel of N series diode. N=VCC/(2.5). by tuning the magnitude of resistor, you can tune the brightness.
best wishes

Hi Nazakat,
555 Timer is the amazing IC for beginners, even me started my hobby circuits with 555 IC.
Here I suggest you a small circuit to practice. You can connect as many LEDs according to your wish.


If you still confused let me know.
