I just bought 7 555ic timers, all of them are faulty? Answered
i bought 7 555ic timer. i tried to blink an led but the output always stays high. when i swapped the 555 by a 556 it then worked.
first i thought that my circuit was wrong. i've verified it countless times all seemed to be good but the pin 3 output was always high. when i used the 556 timer with same components it worked. is the 555 timer at fault or i am missing something?
