heres the circuit..
ok this is what happens.. when i trigger the first 555 the first led goes on but on its timeout the second one doesnt trigger..
but when i take off the first led the second one triggers in the right time.. and the same happens for the third..
is this because the leds diode beaviour? would using an op-amp instead of a transistor fix this? how must the gain of the op-amp be set in such a case?
and if your wondering why i didnt check with some other load i culd only find leds in the lab :S
