Step 4: Configure the Sketch Prepare the Sketch: The Arduino Cloud IoT platform will generate a thingProperties.h file that includes the necessary credentials and variable definitions. Write a sketch ...

This is a tutorial how to send DHT11 sensor data using the Arduino Uno, HopeRF RFM95 LoRa transceiver and The Things Network to IOTA Tangle using Masked Authenticated Messaging (MAM).

How does DHT11 Work? As already mentioned, DHT11 has an NTC thermistor and humidity sensing components. When the temperature changes, the resistance of the NTC also changes. This change in resistance ...

If you call (access) any library or built-in functions in your Sketch code, how you call each function must match its prototype defined in a .h file somewhere. Libraries work the same way.
