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 ...
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 ...
Probably the most complex part of working with Arduino is creating the sketch, a.k.a. writing the code. The Arduino programming language uses a variant of the C/C++ language, so if you're already ...
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… ...
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 ...
Open the Arduino software and paste the Arduino code (the text in the box near the bottom of the post) into a new sketch. Click Sketch > Verify / Compile to make sure the code is properly in there.
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 ...
Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...
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.
