You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the ...

We use the serial monitor to display the data received from the board and one interesting thing you might notice is that the data is already printed in degrees because this is a digital temperature ...

Conversely, the comparator output and the connection to the Arduino’s analog converter (A0) are labeled nodes from the “Output and Labels” menu. The names are significant, including the spaces.

You can, however, enter things into the serial monitor. You can run a canned demo that uses digital and analog output. There is also another sample that uses the serial port.

If you are interested in creating an Arduino wind speed meter or anemometer to monitor the wind strength in your location, you might be interested in this quick tutorial I have put together to ...

The Arduino candy bowl monitor has been created by the team over at Adafruit and allows you to be notified when the candy outside your house has been devoured.

Arduino, by contrast, is not a full computer but a microcontroller. Devices like the Arduino Uno or Nano excel at reading analog sensors, controlling motors, and maintaining precise timing.
