This module features the MSGEQ7 graphic equalizer display filter. It will give your arduino ears. Sound is broken down into seven frequency bands and the peak level for each band can be read. The seven frequencies measured are as follows: 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz..
Circuit Stickers are electronic stickers that you can use to build glowing, sensing, and interactive projects without any complicated equipment or programming skills. All you need is your imagination.
And this is an add-on sticker kit for Circuit Sticker Starter kit, with sound sensor, ligh..
This board is a Dual-tone multi-frequency signaling module decoder for Arduino and gadgeteer. With its audio connector you can decode the crazy funny noises common phones make. If you are not sure what I'm talking about, imagine a home phone while pressing several of its keys. These Touch-Tones have..
This Shield is a Dual-tone multi-frequency signaling module decoder for Arduino. With it's audio connector you can decode the crazy funny noises common phones make. If you are not sure what I'm talking about, imagine a home phone while pressing several of its keys. These Touch-Tones have a specific ..
Add an ear to your project with this well-designed electret microphone amplifier with AGC. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX9814, a specialty chip that is designed for amplifying electret microphon..
This small breakout board couples an Electret microphone
(100Hz–10kHz) with a 60x mic preamplifier to amplify the sounds of
voice, claps, door knocks or any sounds loud enough to be picked up by a
microcontroller's analog-to-digital converter. Each breakout comes
fully assembled and works from 2..
Grove - FM Receiver is a wideband FM receiver module. This module is based on the SX6119, which offers true single-chip voice FM receiver, with a built-in amplifier, VCO, filter and demodulator. The multifunction button provides greater convenience for users to control.
Grove Toy Kit provides an easy way for you to hack and upgrade toys to fit with your own personality. It boosts regular toys with many cool functions like sense of human motion, listening ability, movement detection, OLED display, and more. Thanks for the players of Toy hacking contest, there’re six..
The I2C FM Receiver is a wideband FM receiver module based on RDA5807M series which is the newest generation single-chip broadcast FM stereo radio tuner with fully integrated synthesizer. The RDA5807M series has a powerful low-IF digital audio processor. An integrated headset jack can drive audio de..
Listen to this good news - we now have a breakout board for a super tiny I2S MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This microphone doesn't even have analog out, its purely digital. The I2S..
The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high frequency signal that received from the microphone, and outputs a positive envelop. This will make for Arduino’s signal acquis..
This tiny breakout board features the ADMP401 MEMs microphone. One of the key advantages to this breakout and microphone is the bottom ported input. This means the microphone’s input can fit flush against the enclosure of your project. Plus you will not have to deal with trying to solder the microph..
