How to make an LED blink using a 555 timer? Answered
so im doing a school project and i need to figure out this whole circuit thing. my teacher recommended me this circuit (picture related) but i dont understand it. can anyone help me?
i am trying to do this on a bread board (i think they're called that). i am making LEDs that are blinking using a 555 timer and a BD139 transistor. and some resistors that i dont know the resistance of.
