could someone help me to understand how to read the shifting of bit which will turn on the LED?
for "1<<LED0_BIT" what is the value of LED0_BIT?

I am new to this, please bear with my dumb question.

#define LED_PORT PORTD
#define LED_DDR DDRD
#define LED_PIN PIND

#define LED0_BIT PIND4
#define LED1_BIT PIND5
#define LED2_BIT PIND6
#define LED3_BIT PIND7

#define Leds_on() (LED_PORT |= (1<<LED0_BIT) | (1<<LED1_BIT) | (1<<LED2_BIT) | (1<<LED3_BIT))
