The Great Search: Disc Piezo Buzzer Element #TheGreatSearch #digikey #Adafruit #TheGreatSearch @DigiKey @adafruit
(Video) This week on the Great Search, we’re taking apart a McDonalds McNugget Tetris game given away in China for the 40th anniversary of the Chicken McNugget.
Unsurprisingly, it’s an epoxy blob’d chip that does just about everything! For the background music, a disc piezo is used to make the beeps. We’ve covered magnetic buzzers before on the Great Search, which we use on some of our design for SMT tone-making.
At a 500K build, budget is going to be the most important concern, so instead, we can go for a ultra low cost piezo disc! Let’s take a look at what is available at DigiKey and the differences between magnetic and piezo buzzers.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
