At this point, we are ready to test things. We will start with all the sensors.
Again, we will use the Arduino IDE. Note that we will use the Sensirion library, which is required here to use the soil temperature and humidity sensor. Here is the complete code for this part:
// Libraries
#include <Sensirion.h>
// Pins
int temperature_pin = A1;
int light_pin = A0;
int dataPin = 6;
int clockPin = 7;
// Soil sensor instance
Sensirion soil_sensor = Sensirion(dataPin, clockPin);
void setup() {
// Serial
Serial.begin(115200);
}
// the loop routine runs over and over again forever:
void loop() {
// Test photocell
float light_reading = analogRead(light_pin);
float light_level = light_reading/1024*100;
Serial.print("Light level: ");
Serial.println(light_level);
// Test temperature sensor
float temperature_reading = analogRead(temperature_pin);
float temperature = (temperature_reading/1024*5000 - 500)/10;
Serial.print("Temperature: "...
