I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...

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 ...

Tap code is similar to Morse code but easier to send, learn and read while being slower. It uses a single button and stores the tapped code as a C string for comparison/printing. This library is ...

The readability of your code can make the difference between your project being a joy to work on, or an absolute headache. This goes double when collaborating with others. Having easily parsed code… ...

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 ...

This line sets up pin 2 on the Arduino as an input pin. Here's what the parameters mean: 'd' stands for "digital" (as opposed to analog). ... Python Code to read Analog Sensor on Arduino from ...

The Arduino IR sensor module code is very simple and easy to understand. We are just basically keeping track of whether the input to pin D9 is HIGH or LOW. We initialize our code by declaring two ...
