Sample
Read the light sensor at a regular interval so changes can be observed.
Sensors + display
Plant Monitor
A breadboard prototype that gathers light, temperature, and humidity readings and turns them into clear LCD feedback.

Prototype logic
Small loops, observable results.
Combine
Pair the light value with temperature and humidity measurements.
Display
Present the readings on the LCD instead of leaving them only in a serial log.
int photoPin = A0;
void loop() {
int light = analogRead(photoPin);
Serial.println(light);
delay(1000);
