Sensores en arduinoblocks | Democratizando CANSAT

1. Creamos un programa en arduinoblocks, tipo de proyecto ESP32 / WROOM.

2. Implementamos el siguiente código:

ablocks sensores

3. Vemos el código que genera, que posteriormente lo integraremos en el programa de comunicaciones lora en el emisor. El código que genera es éste:

#include "ABlocks_TinyGPS.h"
#include <HardwareSerial.h>
#include <Wire.h>
#include <Adafruit_BMP280.h>
#include "ABlocks_DHT.h"
