Make some noises to alert you when something interesting (or urgent)\nhappens. Simply connect a Qwiic cable and load up some pre-written code to an\nArduino to start making noises! The board includes an ATtiny84 with custom\nfirmware to control the piezoelectric buzzer over I2C. Utilizing our handy\nQwiic system, no soldering is required to connect it to the rest of your\nsystem. However, we still broke out 0.1\"-spaced PTH pads if you prefer to use\na breadboard to access the board's I2C, power, trigger, and reset pins on the\nboard's edge. A 2.2kΩ pull-up resistor is included on the data and clock\nlines. A set of transistors control the buzzer's volume. At full volume, it\nallows the full current of about ~95mA, which makes it really loud. A flyback\ndiode is included to discharge any energy remaining when the buzzer is turned\noff. For those who want to control the loudness of the buzzer, a footprint is\navailable to solder a custom PTH resistor to one of the transistors. Just make\nsure to cut the jumper labeled \"JP1.\" Two LEDs are also included on the board\nfor power and status. We've written an Arduino Library to control the volume,\nfrequency, duration, and I2C address. There are even examples of how to play a\nquick melody and sweet sound effects! You can download the library through the\nArduino library manager by searching 'SparkFun Qwiic Buzzer,' or you can get\nthe GitHub repo as a .zip to install the library from there manually. For\nthose who want a simple buzz without an Arduino, you can also make noise by\nsimply grounding the trigger pin! We've even ported the library as a Python\npackage! This board is great for adding a simple audible sound to your\nprojects. Pair the board with the Qwiic RTC to make an alarm clock, play a\ntune with the Qwiic RFID, or add a sound effect to your robot. So what are you\nwaiting for?!? Start making some noise in your projects with the SparkFun\nQwiic Buzzer! The SparkFun Qwiic Connect System is an ecosystem of I2C\nsensors, actuators, shields and cables that make prototyping faster and less\nprone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST\nconnector. This reduces the amount of required PCB space, and polarized\nconnections mean you can’t hook it up wrong.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eThe SparkFun Qwiic Buzzer adds simple beeps and buzzes to your projects via I2C.
