ESP32

Get started with the SparkFun analog MEMS microphone breakout board! In this tutorial, we will be connecting the differential MEMS microphone to an Arduino using the WM8960 audio codec.

The SparkFun Audio Codec Breakout - WM8960 is a low power, high quality stereo codec chock full of features. In this tutorial, some of these features by using an Arduino microcontroller to configure the audio codec and pass audio to the headphone or speaker channels.

In our previous Bluetooth tutorial called Sending Sensor Data Via Bluetooth, we showed how to display data from a triple axis accelerometer over the Arduino IDE’s serial monitor. Continuing off of the first tutorial, we are going to expand this project to include more capabilities for visualizing and interacting with your accelerometer data.

SparkFun's ESP32 Environment Sensor Shield provides sensors and hookups for monitoring environmental conditions. This tutorial will show you how to connect your sensor suite to the Internet and post weather data online.
