Send SMS text messages, or hook up a microphone and speaker and use it to replace your iPhone. GPS Shield-GPSisn't as complicated as you might think. With a GPS Shield, your Arduino will always know where it is. Music and Sound MP3 Player Shield- Turn your Arduino into an MP3 player...
—-摘自arduino-star-otto Star名字取自ST和Arduino的缩写合并, Star Otto是ST和Arduino官方合作推出的Arduino Star系列的第一个板子, 板载了STM32F469 MCU, ESP8266 WiFi, micro-SD插槽, 摄像头和LCD接口, USB Host, 立体声麦克风( stereo microphone), 耳机和扬声器接口(headphone and speaker output). 供电电...
In the first part of the review, we checked out the hardware of the M5Stack Tab5 ESP32-P4 IoT development kit and tried the demo firmware, whose user interface allows the user to quickly experiment with the camera, microphone, speaker, WiFi, power consumption, GPIOs, RS485, and more. Si...
The Arduino GSM Shield 2 allows an Arduino board to connect to the internet, make/receive voice calls and send/receive SMS messages. The shield uses a radio modem M10 by Quectel. It is possible to communicate with the board using AT commands. The GSM library has a large number of methods...

The bigger in size and the lower impedance the better as the amplifier chip can accept as low as 2 to 3 ohms. update 05/14 - I grabbed this speaker from my old Samsung today, it is 8 ohms and not loud enough... If you know which one is better, please let me know. ...
Condenser microphones, resistors, capacitors, and the LM386 audio amplifer chip can be easily obtained from most electronic online retailers. Before we show the complete schematic diagram of connecting a microphone to an arduino, we will first show the pinout of the LM386. This way, the connecti...
Addition identification of the active speaker using camera assisted microphone array. The possibility of identifying the active speaker component and the camera automatically turns towards the sound source. The PZT cameras work not limited to the human voice, but it is sensitive to all the vibration...
