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 ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least &#… ...

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.

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.

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

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 ...

There’s one big problem with the Arduino development environment, also known as an IDE: There’s no network hookup to directly share and browse code you’re writing for these little ...
