VMA345 4. What is Arduino® Arduino® is an open-source prototyping platform based in easy-to-use hardware and software. Arduino® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board.
VMA345 7. Software Example 1. Download the VMA345_tutorial.zip and DHT_Library.zip from our website and unzip the VMA345_tutorial.zip into an INO sketch. 2. Open the Arduino IDE and load the VMA345_tutorial.ino. 3. Add the DHT_library to the IDE. 4. Now, compile and upload the sketch. 5. Open the serial monitor. 6. This would be the result. Make sure the selected baud rate is the same as used in the sketch! V.
