Bike Light

thingiverse

This is a holder designed for LEDs. The Arduino code includes variables and settings to control multiple LEDs using a button input. Variables like led, led2, led1, led3, led4, btn, val, btnState, ledVal, lightOn, ltc and interval are defined in the setup function. The pin modes for LEDs and button are also set here. The loop function reads the input value from the button and checks if it's pressed. If the button state changes, the LED status is updated accordingly. Serial communication is initialized at 9600 baud rate.
