Project Details
How It Works
How It WorksThe ESP32 controls 5 LEDs connected to GPIO pins 2, 4, 5, 18, and 19. The code uses for loops to turn each LED ON and OFF in sequence, creating a forward and reverse chaser effect. Each LED is turned HIGH for 200ms, then LOW, before moving to the next LED. The pattern repeats continuously in the loop() function.
Prerequisites
Basic understanding of programming concepts (variables, loops, functions). No prior ESP32 or electronics experience required.
