Each time the interrupt ticks, the macro runs and increases a counter by one. Let the sketch run for a minute or so, and you get an idea of how much time is spent in a specific area of code.

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

As the code for the Nano was derived from the GPSDO code, it is again written in C using the Arduino IDE. The frequency counter code is basically driven by the 1PPS interrupt. When a 1PPS interrupt ...

The purpose of this module is to learn about the Arduino interrupt system. An Arduino tetherball game is created to illustrate the use of interrupts. You'll see that ... are positioned in a circle ...

It’s done by running an interrupt on a timer at a steady rate, and implementing 12 counters, one per note. When a counter overflows, a digital IO pin is flipped.

Geiger counter, it's a word that most people have heard about. I'm sure everyone has seen at least one piece of media featuring the clicking box with a little dial that only tells you when you're ...

“The concept of this board is to build an open, very versatile frequency counter, so it can be used to measure a wide variety of signals.” Built around an AVR microcontroller Atmega328p-AU, the ...
