В ядре Arduino есть встроенная функция для полуаппаратной генерации квадратного сигнала – tone(pin, 

It is nothing but an Arduino Library, which produces square-wave of a specified frequency (and 50% duty cycle) on any Arduino pin. A duration can optionally be specified, otherwise the wave continues until the stop () function is called. How to use tone() Function with Arduino. Learn tone() example code, reference, definition.

20 июн 2020 Привет! Мы уже знаем как извлечь из Ардуино звук. И даже собрали простое пианино tone(SPEAKER, notes[i], times[i]); delay(times[i]); }

Changed the way the note duration is calculated from a suggestion by Paul Stoffregen. v1.2 calculates duration differently for higher tone accuracy and smaller code size. v1.1 added a few small changes (after I got around to actually tested the library first-hand with an Arduino). Get an Arduino that has more timers (if you currently use an Uno/Nano/Mini, 32U4 based or a Mega provide extra timers).

ToneLibrary. Signal Input/Output. This is an Arduino Library to produce a tone on any Arduino pin. Produces a square-wave of the specified frequency (and 50% duty cycle) on any Arduino pin. Author: Brett Hagman.

Arduino™ tones are square waves, providing a simple alternative. But an Arduino™ tone is a square wave with a 50% duty cycle repeated at the desired frequency. It's not very musical, but it is simple.

Arduino Uno; 3x 8 ohm speaker or old headphone speaker; 3x 220Ω resistors; One of the Arduino MIDI Interfaces; Breadboard and jumper wires; The Circuit. This circuit effectively creates three Arduino MIDI Tone Modules form one Arduino. This works (with the right code) as the tones are created using one of the Arduino’s timers to create a square wave on an output pin Playing music in the arduino introduces a function known as tone(). This function controls your ability to play music.

First of all - You can drain max 20mA via pin, when one of the pins is HIGH and the other LOW, there is 5V between them, so there should be at least 250 Ohm
