The Seeds of Innovation: Smart Agriculture

STORY

—

In a nearby town, Miguel helps his father maintain a small greenhouse. The weather often changes unexpectedly, harming their crops. With Captain T's help and TRIOE sensors, Miguel learns to monitor environmental conditions in real-time.

Basic Arduino Functions

void setup()

Runs once when Arduino starts - initialization code

void loop()

Runs repeatedly after setup() - main program logic

delay(milliseconds)

Pause execution for specified time in milliseconds

pinMode(pin, mode)

Configure pin as INPUT, OUTPUT, or INPUT_PULLUP

digitalWrite(pin, value)

Write HIGH or LOW to digital pin

digitalRead(pin)

Read digital value from pin (HIGH or LOW)

Serial Communication

Serial.begin(9600)

Initialize serial communication at 9600 baud rate

Serial.print("text")

Send text to serial monitor

Serial.println("text")

Send text with newline to serial monitor

Serial.available()

Check if data is available to read from serial

I2C Communication

#include <Wire.h>

Include Wire library for I2C communication

Wire.begin()

Initialize I2C communication as master

0x76, 0x3C

Common I2C addresses (BME280: 0x76, OLED: 0x3C)
