<aside> 🔴 Summary: I thought I would have an easier time for Week 2, since I accidentally did some Labs in advance, even though I did them ... kind of wrong anyway ... but the effort should be counted. But they didn't.

Day 1
Day 1 — I started Week 2 with Arduino connection woes. I have been using the Web Editor and maxed out my trial time, found out I can easily download the program and have unlimited use for free. I installed it and the process took a ridiculously long time ... so I cancelled it. This was my first mistake.
took me a while to figure out I was on the wrong digital pin
to trouble shoot I: checked the resistor values
checked the LEds legs
replaced the legs
void setup() {
pinMode(2, INPUT); // set the pushbutton pin to be an input
pinMode(3, OUTPUT); // set the yellow LED pin to be an output
pinMode(4, OUTPUT); // set the red LED pin to be an output
}
void loop() {
// read the pushbutton input:
if (digitalRead(2) == HIGH) {
// if the pushbutton is closed:
digitalWrite(3, HIGH); // turn on the yellow LED
digitalWrite(4, LOW); // turn off the red LED
}
else {
// if the switch is open:
digitalWrite(3, LOW); // turn off the yellow LED
digitalWrite(4, HIGH); // turn on the red LED
}
}
