V=I/R

u need to make another circuit from where ever u tap the electric from and convert the voltage to 6V or 9V then only connect to that circuit u showed. usually what i do is use variable resistor for our factory usage la...for car MIGHT be the same...but be cautious that if the I is too big value might fry something in the car...

so many thing to think about... damn... maybe i need to dig more info 1st...

if u wan we can work further on this...later on can bulk
i have another project on hand...YAB n kanjiloo knew about it...wanna make VS bought some stuff and have yet to solder as my circuit diagram is not properly configured yet...running multisim but somehow cant get it to show exact output that i wan...maybe i did something wrong somewhere lolz

V=I/R?

sorry its V=IR
told u i have return to the BOSS

oic... haha, wait me dig more info thn we discuss la...

wow, TQ for the link but too much word, balik rumah baru baca...

Well, i don know how is your LED strip,
1. is it single +/- for multiple LED or
2. separate +/- for each LED? how many LED in total?

For pic 1 (555 timer + counter 4017 IC]
This one is counter circuit, 555 is timer and output clock to trigger 4017 switching. each output goes high in turn. So is not suitable if ur LED strip is (1). Output voltage will follow more or less same as Vcc input, means if u provide 6V, output is around 5-6V max only, so this voltage enough to power ur LED or not? i dun think so.

For pic 2 (fading circuit)
Again this one is 555 timer + switching transistor which C1 (100uF) act as a main 'fading effect' component to this circuit. C1 provide current is exponential rate so that the transistor ON-OFF exponentially, and LED will looks like has 'fading effect'.

Voltage supply is not a crucial part for this circuit, as we have a lot of DC-DC converter AKA voltage regulator (3 pins like trans too) convert from higher voltage to let say 5V (safe operating voltage for IC and LED). But the most crucial thing is u must know the current consumption and power consumption of ur LED, forward voltage drop of LED, connection o LED (series or parallel) which in turn affect ur component selection. I dare to say 4017 alone will not be able to provide such high power for ur LED strip and will burn if certain current exceeded, same as transistor as well. So don simply plug and play if u dun have electronic background, and sorry to say that, to guide you by words alone is simply too difficult for me.

the master has SPOKEN!

wokeh. sms me when u come ober.

oic... the led strip which i mention is mostly nowdays ppl selling those type 1210 or 5050 , i think its 3 led per strip if not mistaken.

aiya, means those above circuit cannot be use, even can use also might not able to power up the LED...

so hows to to a fading circuit correctly for the led strip?

Today I din come TT la, bcoz currently now i at Kuantan....VS not bad la...haha....

Hi Bro...
Yu planning DIY Running LED Turning Signal Indicators?

If so, me rber oledi got those that fit onto wing mirrors...shape of a running LED arrow...

2nd plan?
Fading out cabin lamp after closing door?



ps. Me juz guessing nia...wild guesses...

weird why ur vacuum meter only got 10 bar ~ ??

1.0 not ori meter,vacumm picture when on aircon

-1.0 bar = -30 inHg

How many bars you wan
