SKU: LB-LR0289 | Brand: Little Bird

With the passive buzzer you can control the volume by PWM. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than...

SKU: AF-1739 | Brand: Adafruit

This large enclosed piezo element (30 mm diameter) converts vibration to voltage and voltage to vibration, making it useful both as a buzzer for generating tones and as a sensor for detecting knocks and impacts. The e...

SKU: AF-2831 | Brand: Adafruit

This Photo Transistor Light Sensor is a simple sensor that detects ambient light. It's kind of the opposite of an LED - when light hits the little chip inside, it induces current to flow from the long pin...

SKU: AF-1740 | Brand: Adafruit

This small (14mm diameter) piezo element is nicely enclosed so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tone...

SKU: SF-SEN-00246 | Brand: SparkFun

This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).

SKU: SF-SEN-09196 | Brand: SparkFun

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple...

SKU: LB-LS6972x2 | Brand: Little Bird

A compact stereo speaker pair for small audio projects, handheld devices, and embedded builds. Each 45mm driver is rated at 4Ω and 3W, delivering clear, balanced sound in a slim form factor. Pre-wired with a PH2.0 plu...

SKU: SF-COM-08635 | Brand: SparkFun

Small electret microphone. Useful in acoustic and audio applications. Documents: Datasheet Example Audio LED control project by Adam Greig

SKU: LB-LS0633 | Brand: Little Bird

A pack of 50 through-hole photoresistors (light-dependent resistors / LDRs) with a 5 mm diameter sensing element. These components change their resistance based on the amount of light hitting the sensor — resistance d...

SKU: AF-1935 | Brand: Adafruit

That's one tiny microphone! At about the size of a mature aphid, this wired Electret Microphone is perfect for your FONA. This microphone's very similar to our PCB-mount Elecret Microphone but is significantly sma...
