¶ Seven-Color Flash LED
¶ Overview
In this experiment, we will learn how to use the seven-color flash LED module.
¶ Seven-colorflash led module
Clear 5mm LED for direct operation from 5V. The LED color automatically cycles through a seven-color sequence. The 5 V supply connects to the ‘S’ pin and ground on the center pin.
This LED module is equipped with three pins, yet only the two pins adjacent to the "S" label are functionally required. If the LED fails to light up during debugging, please verify whether the hardware wiring is correct.
