![]() If you want to play different pitches on multiple pins, you need to call noTone() on one pin before calling tone(). ![]() A duration can be specified, otherwise the wave continues until a call to noTone (). The LED blinks, but the buzzer doesn't sound, which is weird since the LED and buzzer commands are interspersed between each other in the sketch. The Arduino programming language Reference. Generates a square wave of the specified frequency (and 50 duty cycle) on a pin. This Arduino synth uses the Tone function to use the internal timers. So between each tone, additional codes can be added to. Using Arduino Networking, Protocols, and Devices. Instead of the delay function, the code uses millis function to obtain the time. The beep sound has a duration of 3 seconds and a frequency of 1500Hz. When the sketch runs, everything works just fine. The Arduino beeping timer generates a beep tone with an interval of 30 minutes between each beeping sound. 5 Plays multiple tones on multiple pins in sequence. Note that the duration of each tone is the same as the delay that follows it. Arduino Tone Music: This is an Arduino project that uses the native tone generating ability of the Arduino to make music. I'm very new to Arduino (as in I had to learn it this weekend for a school project) and I'm having trouble getting my piezo speaker to make a sound for an alarm clock. The sketch below plays a tone on each of the speakers in sequence, turning off the previous speaker first.
