I have 10 yellow-colored LEDs and ten 220 ohm resistors. I don't have any power source except the Arduino's 5 volt itself.
Is it possible to power all the 10 LEDs using the 5 volt equally? Or will the volts slowly diminish as the LEDs are powered along a series circuit? Also, is it possible to use only one resistor in the series or do I need to use a parallel circuit with one resistor after every LED?
Please help, I'm completely new to electronics and building a arduino project for my school expo.
