Electronics urgency again!!

Can LED's be wired in series?? if so, what pin to the next?? thanks

SMD's actually

 

[Andy_con]

not the best way, they will get dimmer and dimmer as u go along

It'll work fine....providing that the sum of the forward voltages of the LED's is less than the power supply.

To figure out your resistor, subtract the load voltage from the supply voltage and then use the R=V/I equation.

And you'll need to wire them:

V+ --/\/\/\/-- (AK) (AK) (AK) --- GND

no......

plus to plus, neg to neg

best results

 

[Dink]

yeah plus to plus and neg to neg

just use the total forward current when finding a resistor

although series resistors are no good for luxeon emmiters lol

 

[sn00p]

no......

plus to plus, neg to neg

best results

Erm. Diodes only allow current to flow in one direction....

My diagram above is right.

 

[Dink]

yeah if you connect them in parallel they will just share the current
