• What is the logical first test?

• a. LED

                        Test1:
                     

                     

                        Code:

                       void setup() {
                             pinMode(13, OUTPUT);
                       }

                       void loop() {
                            digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
                            delay(1000);              // wait for a second
                            digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
                            delay(1000);              // wait for a second
                       }

                       Test2:

                        
                       Code:

                       void setup() {
                             pinMode(16, OUTPUT);
                       }

                       void loop() {
                            digitalWrite(16, HIGH);   // turn the LED on (HIGH is the voltage level)
                            delay(1000);              // wait for a second
                            digitalWrite(16, LOW);    // turn the LED off by making the voltage LOW
                            delay(1000);              // wait for a second
                       }

• b. humidity, temperature sensor

                      Code:

                       // Include required libraries
                       #include <SPI.h>
                       #include <string.h>
                       #include "DHT.h"

                       // DHT11 sensor pins
                       #define DHTPIN 13
                       #define DHTTYPE DHT11

                       // DHT instance
                       DHT dht(DHTPIN, DHTTYPE);
                                       
                        void setup(void)
                       {

                        // Initialize DHT sensor
                        dht.begin();

                        Serial.begin(115200);

                        }

                        void loop(void)
                        {

                        // Measure the humidity & temperature
                        float h = dht.readHumidity();
                        float t = dht.readTemperature();
 
                        // Transform to String
                        String temp = String((int) t);
                        String hum = String((int) h);
 
                        Serial.print("Temperature: ");
                        Serial.println(temp);
                        Serial.print("Humidity: ");
                        Serial.println(hum);
                        Serial.println("");
                        delay(1000);
                        }
