Buzzer Project #1 - On and Off
Buzzer Project #2 - Simple Music and Tones
In this activity you will see how to use the tone functions to program simple sounds and songs. This activity will highlight the following code; tone(pin, frequency, duration)
pin = the # of the pin frequency = the frequency, pitch or note duration = how long the note lasts
pin = the # of the pin frequency = the frequency, pitch or note duration = how long the note lasts
After you get it to work, change some of the parameters like the delay time.
Buzzer Project #3 - La Cucaracha (creating a tone library)
Twinkle Twinkle Little Star Code - Scratch/mBlock
Buzzer Project #4 - Shave and A Haircut Variation
In this project you will experiment with the Arduino IDE. You learn how to play a melody by including an array that declares the notes. Here you will need to include the musical notes as part of the program.

Buzzer Project #8 - Button Piano
Follow the wiring sketch to wire the device correctly. Then start the Arduino IDE (app) and then type in the code as shown. Once done, try to play Mary had a little lamb. Be sure to check all the wiring. Use the small buttons in your kit. Although the code is written for 9 buttons and sounds, you will only use 5 buttons.

Piezo buzzer is an electronic device commonly used to produce sound. Piezo buzzer is based on the inverse principle of piezo electricity discovered in 1880 by Jacques and Pierre Curie. It is the phenomena of generating electricity when mechanical pressure is applied to certain materials and the vice versa is also true. Such materials are called piezo electric materials. Piezoceramic is class of manmade material, which poses piezo electric effect and is widely used to make a disc, the heart of piezo buzzer. When subjected to an alternating electric field they stretch or compress (vibration), in accordance with the frequency of the signal thereby producing sound. Potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. Photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. |
