COMP $1045$ LAB $1$

Circuit diagram: Connect a blue LED on a bread board. Connect the anode side to port $13$ on the arduino and the Cathode to the ground.

Source code: Use this code to test the above circuit.

int blueLED $=13$; void setup$()\{$

pinMode$($blueLED$,$ OUTPUT$)$;

$\}$

void loop$()\{$

digitalWrite$($blueLED$,$ HIGH$)$; delay$(1000)$; $//$ Wait for $1000$ millisecond$($s$)$ digitalWrite$($blueLED$,$ LOW$)$; delay$(1000)$; $//$ Wait for $1000$ millisecond$($s$)$

$\}$

Level $1$: Modify the program to make the LED flash slow three times $(1000$ mS delay$),$ then quickly three times. $(100$ mS delay$)$

Level $2$: Modify the program to flash your initials using Morse code $($See chart below$).$ A $$dot$$ would have the LED on for $100$ mS and for a dash the LED would be on for $1000$ mS

Level $3$: Write a program that alternates between the blue LED$1$ and red LED$2,$ to simulate an emergency vehicle.
