Hello everyone, I have a question related to the arduino starter kit project "Love-o-meter".
why are the 220 ohm resistors attached to the cathodes of the leds when the voltage/current flows through the anode of the leds?
I thought that the resistor goes through the anode to reduce the amount of voltage/current going through the led diode and prevent it from burning up.
Is it different when the led diode is connected directly to 5 volts and not a pin? Can someone explain?
