These Miniature Buzzers are a low cost miniature transistor oscillator 6V buzzer with flying leads. They have a single-tone frequency of 400hz and a sound output of 75dB @ 200mm. They are rated for 4V - 8V (6V nominal) and a current of 25mA and the driver circuitry is built in. These buzzers are supplied as a pack of 10.

The buzzer unit is L23mm x W17mm x H15.5mm, with fixing centres at 27.5mm, which gives a total length measurement of 33.5mm. The colour-coded (red & black) flying leads are 100mm. To ensure optimum performance and to protect the buzzer, ensure that the supply (e.g. batteries) is connected in the correct configuration.

This is a through-hole version of the popular SparkFun Electronics Simon Says kit. The kit lets you make your own Simon Says game, where you have to copy a pattern that gets more and more difficult until you fail to copy it correctly. This version comes with an ATmega328 processor that is pre-programmed with the Simon Says code (the source code is provided below if you want to re-write it!). All components are through-hole, making this kit great for beginners. When building this kit, you'll have a chance to solder a 28-pin microprocessor, LEDs, battery clips and more.

After you have successfully assembled the kit, you will have a greater knowledge of through-hole soldering and the tools, techniques, and terminology required to populate your own PCB prototype. You will have a development platform with 5 outputs (LEDs and buzzer), 5 inputs (buttons), and serial for debugging. And, of course, you'll have your very own Simon game! Checkout the great assembly instructions. The kit even includes batteries! Assembly time varies, but for a true beginner with no soldering experience, the kit can take 20-40 minutes to assemble.

Kit Includes:

1x ATmega328 - pre-programmed with Simon firmware

1x Buzzer

2x 0.1μF Cap

1x 10K Resistor

4x LEDs (blue, yellow, red, green)

2x Slide Switch

4x Battery Clips

2x AA Batteries

1x Button pad

1x Bezel

4x Standoffs and screws

1x Assembly instructions.

Note: This ATmega328 comes pre-programmed with the Simon code as well as the STK500 serial bootloader. This serial bootloader will allow you to re-program the Simon game using the Arduino development environment if you want to change the code for your own. There is not direct support under the Arduino IDE but the 'LilyPad Arduino w/ ATmega328' should allow you to reprogram the board using Arduino. You will need a serial to USB converter such as the Breakout Board for FT232RL USB to Serial to program the reprogram the board from the Arduino environment.
