How to blink{breathing style} LED$ while you are playin re4/mgs/crysis

Step 2 Building the gadget

To build it first take out your breadboard.Mannnnn people who dont know how to solder should buy this piece of bread!!!

After watching the diagram plz try to put all components by yourself it will help you on the future

thank you shams for your answer to my question (which was stupid I realize now, but I am a philistine in electronics). I will try your schematics then. Do you know if this circuit can be modified so as to have two alternating fading leds ?

[marcia09]

I mean when one led fades out, another led lights up slowly, and when it fades out the first one lights up, etc. I succeeded in making this with the bill bowden circuit using an op-amp kia 4558 but I´m not completely happy with the results and would like to try something else.

u can do it with a cmos ic named 4047.......it got 50% duty cycle on each out put.......just add the transistor capacitor circuit on the output just like 555

[shams]

No there is no stupid questions in electronics.................what really do u mean by alternating fading leds ?

[marcia09]

on your schematic, the capacitors 1 and 3 have no indication of polarity. Does it mean it doesn´t matter and we can mount them both ways ?

[shams]

capacitor 1 got polarity it's on the schematic..but 2 and 3 dont cuz they are ceramic cap....But the big one(white one) got polarity...the pin which is connected with the collector of the transistor is +...............dont ever reverse ur electrolytic cap...on high current it will blow on low it will be damaged and it will become slowwwwwwwwwwwwwwwwwwwww

i suck at scematics.. can you explain this a little to me, to help me learn?

[shams]

do you understand what is capacitor,resistor,led and chip????.........

[momsgonnafindme]

yeah.. but like the chip pins are messed up so that confuses me sometimes. also how do you hook up the capacitor?
