int led1 = D2;
int led2 = D3;

void setup() {
    
   pinMode (led1, OUTPUT);
   pinMode (led2, OUTPUT);
    
}

void loop() {
    
    digitalWrite(led1, HIGH);
    digitalWrite(led2, LOW);
    delay(1000);
    digitalWrite(led1, LOW);
    digitalWrite(led2, HIGH);

Process 

If appropriate, if you ran into difficulties and/or if you experimented (went beyond the materials), describe how you arrived at the outcome. Outline the process you underwent to reach the outcome (experiments, hacks, tests, refinements, iterations, failures)
I went through the slides and reading material. Followed the instructions. I enjoyed the circuit designing part. Experimented a bit by moving connections here and there and tried to understand the effect of different sections. Connected two LEDs to different pins. Also, tried connecting two LEDs to the same pin using the series connection. Observed that LED was blinking very dim due to low current.

Reflection

Reflect on the process of making this project. What did you learn? What would you do differently?

I went through the slides and reading material. Followed the instructions. I got to revisit the concept of LED and its different types. Also, got the concept of using a breadboard. Most importantly, learn the concept of microcontrollers and their different pins- digital/analog and input/output. Powering and grounding of microcontroller and whole circuit.
