I know it's really really basic but I legit got this thing a day ago, so I feel like that's fair.

So basically it's just something to monitor watering plants. I saw a girl on tiktok basically make a plant tamogachi and I thought that was really cool.

The water sensor corrodes easily so every 10 seconds, it's goes on high power, runs the rest of the code, and then goes back to low power. Until 10 seconds later. 

The problem I'm running into is that it kinda ramps up. it take a long time to get to the actual current water moisture. So unless you were drowning this plant, it would tick up very slowly.

when it reaches certain values, the led is supposed to change colors. So it's red (dry asf), yellow (warning), green (okay), and blue (lots and lots of water).

here's the code, once again it's very simple.

Also, regarding the title. Technically the traffic light was my first project, because I was following the freecodecamp 10 hour guide but I kinda fell off at hour 5.

Eventually, in the future, I'd like to make a bipedal autonomous robot, that's like 2 or 3 feet tall. So I gotta start somewhere.

for rule 2: Elegoo 2560 mega starter kit. 

    int agua = A0;
    int power = 9;
    int red = 2;
    int green = 3;
    int blue = 4;
    int x = analogRead(agua);
    
    
    void setup() {
      // put your setup code here, to run once:
    Serial.begin(9600);
    pinMode(agua, INPUT);
    pinMode(power, OUTPUT);
    pinMode(red, OUTPUT);
    pinMode(green, OUTPUT);
    pinMode(blue, OUTPUT);
    }
    
    
    void loop() {
      // put your main code here, to run repeatedly:
    digitalWrite(power, LOW);
    delay (10000);
    digitalWrite (power, HIGH);
    analogRead(agua);
    Serial.println(analogRead(agua));
    if (x >= 600) {
      digitalWrite (blue, HIGH);
    } else if (x < 410) {
    digitalWrite (red, HIGH);
    } else if (x > 430) {
    digitalWrite (green, HIGH);
    } else if (x > 410 & x < 430) {
    digitalWrite(red, 255);
    digitalWrite(green, 255);
    digitalWrite(blue, 0);}
    }

My first project.
