Play simple tones or even melodies - add an audible alert to your project.

A common and insanely versatile timer/oscillator from TI - blink an LED, generate tones, triggers and thousands of other uses.

This tiny (0.35″×0.45″) U1V10F5 switching step-up (or boost) voltage regulator efficiently generates 5 V from input voltages as low as 0.5 V. Unlike most boost regulators, the U1V10F5 automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 45 V and efficiently reduces it to 5 V. The board measures...

The Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once.

According to The Internet, 95% of electronic projects can be done with an op-amp or 555 timer chip. We're not so sure about it, but the 'triple...

The sound trigger listens to the noise level in your room, and sends an ON signal when it gets over a certain level. You can make that threshold louder or softer using the included screwdriver. We like to use it with an LED to light up your room when you snap your fingers.
