LED blink
Your board contains one user programmable LED diode (see schematic). Let's try to controll it using the followng programm:
#define LED_Yellow 13 // select the pin for LED
void setup()
{
pinMode(LED_Yellow, OUTPUT ); // this pin is an OUTPUT
}
void loop() // endless loop
{
digitalWrite(LED_Yellow, HIGH); // make it visible
delay(1000); // wait 1000 ms = 1s
digitalWrite(LED_Yellow, LOW); // turn off
delay(1000); // wait again
}
How it works
It is necessary to determine whether the certain pin will be configured as an INPUT or OUTPUT one. This is done in Setup section using the command
Your turn
Connect Your own LED on the experimental breadboard. Connect the LED to the pin D2, it will be assigned with number 2 in Your program digitalWrite(2,HIGH).
Change the program to blink with both LEDs - Your and the onboard. Can You program them tu blink mutually like on the railway crosses?
