How To Wire Multiple LED's in a Series Circuit !!

If your LEDs dont light up here are a couple troubleshooting problems that you may have

1) 1 or more of the LEDs are facing the wrong way
2) They light up but are very dim - Not enough voltage or you could have the LED the wrong way
3) LED feels very warm to the touch - LED is the wrong way around or doesnt have the right resister and should be fixed instantly before it burns out

bang those skins...not related to video but rock on if you still playyyyyyyy

So I can soder how ever many leds I want with only one resistor? Are there different resistors?

Can i connect them all to a 9v button cell battery?

@TheRuralGrowerMan you have to make sure your power supply is capable of providing power to that many LEDs. A power supply only provides a certain wattage (P=E*I) and you don't want your LED circuit to exceed that wattage. 260 is a lot of LEDs and at 20mA per LED that's probably over 30 watts. so a 12 volt power supply would have to provide close to 3 amps.

hi, great help, 1 question, does it matter how many leds i string together, if i wanted to make a board of say 260 led's do i have one resistor, 1 power supply of 12v?

ok brother,thanks for help

@nina1qaz :I would say that no special wiring. Jjust make sure it has enough wire thickness to handle load. The only thing you need to get to A-Z is just a longer wire.

@osamamoto I'm not sure if this will be the help you need but make sure you use a solder with built in flux. It makes the solder stick to wire and keeps it from running and able to stick.

@tomx63 Thank you sir lol.

what is the resistance of the resistor
