The Arduino Nano 33 BLE Sense Rev2 runs on the Arm Mbed operating system, which is open-source, easy-to-use software for IoT applications. This operating system is specifically designed for Arm Cortex-M-based microcontrollers and includes security, storage, connectivity, RTOS, device management, and drivers for sensors and input/output devices.
The hardware platform is equipped with several onboard sensors that can detect color, proximity, motion, temperature, humidity, audio, and many more. The board can connect to Bluetooth Low Energy wireless connectivity to transfer onboard data. The BLE module from U-Blox has an internal antenna and can transmit data between different devices using the ArduinoBLE library.
The device has an omnidirectional digital microphone that can capture and analyze audio in real-time to create a voice interface for any IoT project. The sensor uses the Pulse Density Modulation library to use these functionalities. Here is a detailed guide on how to control the onboard RBG LED light with a microphone.
For interested professionals, the Arduino Nano 33 BLE Sense Rev2 is currently available for purchase at $40.50.
