QBuzz Quickstart Guide



The Basics:


The QBuzz is a standard buzzer, but in a cool plug and play format!  It can make sounds/frequencies higher than we can even hear!




First off, if you don’t know how to solder, go here to learn the basics so that you are thoroughly prepared to assemble your kit.


Parts in Kit:


Qtechknow QBuzz PCB (Printed Circuit Board)

Piezo Buzzer - Small

Male Headers (10)


Tools Needed to Assemble:


Soldering Iron

Rosin Core Solder

Safety Glasses

Safety Mask

Vice or Third Hand


You will need to get on your own:


Arduino Leonardo with micro-B USB Cable


Arduino Uno with USB-B Cable


When using lead, take precautions like:


  • Make sure to wash your hands with soap and water twice after you solder
  • Don’t eat the solder
  • Don’t touch your face or eyes after touching the solder
  • Wear a mask to prevent the solder smoke to come into your mouth, or to prevent you from inhaling it
  • When working with hot solder, you especially want to wear eye protection


Assembling the Kit:


Take out the QBuzz PCB out of the the bag and put face up into a vice or third hand.

The buzzer is labeled on the top with a small plus, and on the bottom in the PCB with a + and -.


Insert the buzzer into the copper holes corresponding.  Make sure that you are putting it in the right way!

Flip the PCB over and put it back into the vice or third hand face down, so that all of the leads show on the back.   Bend the leads outwards in different directions.

Put your soldering iron on one of the junctions where there is a copper hole, and one of the buzzer legs popping through it.

Wait three seconds, and then take your solder, touch it briefly to the junction, and then take your soldering iron away.  The junction should look something like these volcano shapes:

Repeat this process once more to the other copper hole with a buzzer leg popping through it.

Trim the leads so that they don't poke you.

Take the 10 pin male header and put it into SCL through D8.  It is shown below in the picture.

Place the QBuzz on top of these pins.

Solder in place.  But make sure that you don’t put too much solder in, because that can cause the QBuzz to be permanently installed on your Arduino!

Wait for the QBuzz to cool off (around 20-30 seconds), then pull out of the Arduino sockets.  Now you are finished soldering your QBuzz!




If you haven’t downloaded the Arduino IDE, go here to download the latest version.  If you haven’t installed drivers for the Arduino (haven’t downloaded the software yet, or haven’t done this step yet), read the following table:


If you have...

Arduino Uno

Arduino Leonardo


No drivers needed, proceed to the next step

Go here, then proceed


Go here, then proceed

Go here, then proceed



Put your QBuzz in pins SCL through D8, like before.

Plug in your Arduino with your USB cable (USB-B on the Arduino UNO or earlier, and USB-microB for Arduino Leonardo) to your computer.  Download this zip file and unzip onto your computer.  If you are on a Mac, double click the folder labeled “FishBank-QBuzz-Example-Code-f78ead3”, double-click the file named “QBuzzSounds.ino”, then press OK when the dialogue box pops up. If you are on a Windows computer, press Save instead of Open when you press the download button, double click the folder labeled “FishBank-QBuzz-Example-Code-f78ead3”, double-click the file named “QBuzzSounds.ino,” and then press OK in the pop up box.

The Arduino IDE should open up with the QBuzz Sounds sketch.  This sketch will make the buzzer pitch go up and down.

First, make sure to select the board that you are using from Tools > Board.

Then, go into Tools > Serial Port, and select the correct COM/Serial Port.  On a Mac, the usual Serial Port will be /dev/tty.usbmodemfa131.  Any small variation of that will be fine.

On Windows, the COM Port will usually be COM 4, and anything lower or higher might work.

Here are the basic buttons/functions in the Arduino IDE:

Now let’s upload the sketch/code to the Arduino.  Plug one end of the cable into your Arduino, and then the other end into your computer.  Press the Compile + Upload button (Verify if there is any errors in the code, and then upload the sketch/code onto the Arduino), and the program will run on the Arduino.

You should hear your new QBuzz working!  Hope this inspires you to make a cool project (with lots of sound)!
