Arduino Uno LED Chaser

The Arduino Uno LED Chaser is a circuit where multiple LEDs light up in sequence, creating a chasing effect. It typically involves programming the Arduino Uno to control the LEDs' on and off states, creating a visually appealing pattern.

wheres the resistance for each of them ?

[@Projectslearner]

There is no problem , led will be works directly gpio pin of microcontroller

[@user-wl9hz6cb4u]

@@Projectslearner oh thats good to know , I always thought you needed some sort of resistance to make it work

[@Arduinoprojects786]

Leds can be directly connected with Arduino pins but resistors having value 220 Ohm recommended for smooth operation. Because if Leds become short circuit the Arduino pin will be damage.
