Outcome

Exercise 1.1- Make LED Blink on and off every 3 seconds.

The introduced code for the light blinking includes a loop that directs the light to illuminate (digitalWrite(ledPin, HIGH)) for a duration of three seconds (delay(3000)), followed by deactivation (digitalWrite(ledPin, LOW)) for an additional three seconds. As a result, the light alternates between on and off states at three-second intervals. 

Code and video are below

Exercise 1.2 - Change the program to blink on and off 5 times then stop for 3 seconds. Each blink should be 0.5s (a half second)

 I modified the code by incorporating a nested loop within the loop() function to achieve five cycles of the light blinking on and off. Each blink is separated by a brief pause, and there's an additional 3-second delay after completing the five blinks.  

Code and video are below

Exercise 1.3-  Go back to the original program. Now add a second LED to the circuit.   Program the LED’s to alternate blinks i.e. when LED 1 turns on, LED 2 turns off, then when LED 2 turns on, LED 1 turns off.

I added another Led into the D3 input and then rewrote code 1, where I made them high and low alternatingly, with a small delay in between

Reflection

Labelling the code helped me have a better understanding. Although I am still struggling with the concepts of loops, especially void loops, I think I can better comprehend writing basic code. My code can be longer, but it will get the job done!
