Small electret microphone. Useful in acoustic and audio applications.
The Electret Mic Breakout translates amplitude (not volume) by capturing sound waves between two conducting plates (one a vibrating diaphragm and the other fixed) in the microphone and converting them into electrical waves. These electrical signals are then amplified and picked up by your microcontroller’s ADC.
The ADMP401 is a high quality, low cost analog output bottom ported omnidirectional MEMS microphone. That was a mouthful! A wide frequency response and low current consumption makes it perfect for embedded applications.****Check for a breakout board below.
The SparkFun Photon RedBoard has been based around the P1 Particle Module. Each P1 comes pre-loaded with Particle OS firmware and includes their basic cloud service. With a built-in antenna and a uFL connector, the P1 makes it so you don’t have to stress over the optimization of RF designs.
Communication with microSD cards is achieved over an SPI interface. The SCK, DI, and DO pins of the microSD socket are broken out to the ATmega168/328’s standard SPI pins (digital 11-13), while the CS pin is broken out to Arduino’s D8 pin.
The SparkFun Big Red Box Proto Board is a large, custom made PCB that has been specifically designed to be used with and installed into our Big Red Box. This board features a large prototyping area with exactly 1,488 solder points (yes, we counted).
EasyVR 3.0 is a multi-purpose speech recognition module designed to add versatile, robust and cost effective speech and voice recognition capabilities to virtually any application. EasyVR is the third generation version of the successful VRbot module and builds on the features and functionality of its predecessor. In addition to the EasyVR 3.
The SparkFun Inventor’s Kit for Photon is the latest and greatest in Internet of Things kits. Whether you’re a software developer just getting in to hardware, an EE learning software, or somewhere in between, this kit will help you get your projects hooked up to the Internet in no time.
Sometimes when you have too many choices, it’s hard to make a good decision. In fact, there are times when you just want a bag of LEDs, just one of each, that’s all you want. Well here you go! The LED Mixed Bag contains one each of our 10mm LEDs. This is a great way to sample each one and decide what your project really needs.
The amplifier on the breakout has a gain of 67 and more than meets the bandwidth requirements of the mic. The amplifier’s AUD output will float at one half Vcc when no sound is being picked up. The amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational...
The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted with a through-hole resistor, to change the threshold of the binary (gate) output pin as well. Check the hookup guide below for more information about setting gain.
To get the SparkFun Soil Moisture Sensor functioning all you will need is to connect the VCC and GND pins to your Arduino-based device (or compatible development board) and you will receive a SIG out which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist...
