resistor. A common LED diode voltage is approximately 2.5V, while the current varies from 1 to 20mA depending on the type of LED.
The BIGAVR6 uses LEDs with current I=1mA.
There are 86 LEDs on the BIGAVR6 development system which visually indicate the state of each microcontroller I/O pin. An active
LED indicates that a logic one (1) is present on the pin. In order to enable the pin state to be shown, it is necessary to select
appropriate port (PORTA, PORTB, PORTC, PORTD, PORTE, PORTF, PORTG, PORTH, PORTJ PORTK or PORTL) using the DIP
switch SW12.
