He started out with an Arduino and a simple microphone. He wrote a basic sketch to read the input from the microphone and output the perceived volume over a Serial monitor as a series of asterisks ...

A lot of phrases surrounding phones don’t make sense anymore. With a modern cellphone, you don’t really “hang up” and there’s certainly no “dial” to be had… ...

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 button is not pressed and 1 that the button is ...

pinMode' is a built-in Arduino function that sets how a given I/O pin on the Arduino behaves - either input or output. In this case, we're telling the Arduino to use pin LED_BUILTIN (13) as an ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

The Arduino can also read from an analog sensor, which can't be done on the Raspberry Pi. The Raspberry Pi is a microcomputer you can write code directly onto the device.

The BearDuino sketch code drives the servo based on serial input sent from the PC, mapping the values to a range of 180 degrees of motion. Most of the complexity is on the Windows code side.

You can also modify the code to include additional features, such as automatic frequency adjustment based on sensor input. Jump over to the official Arduino blog for more details.

Spark Devices wants the inclusion of WiFi in devices to be a matter of when, not if -- and if its new Spark Core gets to market as planned, tinkerers might never have a moment of doubt. The tiny ...
