Hardware Overview
How does it work?
Vibra sense Click is based on the 801S, a shock sensor from Sencera. To eliminate signal noise, the sensor's output uses a pull-up configuration alongside quad 2-input NAND Schmitt Trigger, the CD4093BC from ON Semiconductor, which is necessary as the output must become a square wave. Two of its 2-input gates and the potentiometer are used to clean the noise and set the interrupt threshold. With this potentiometer, you can set the force necessary to activate the Vibra sense Click. The sensor is extremely sensitive
to movements such as a light tap or vibration. Unlike many other sensors that use a mechanical switching element, this one uses a resistive element that changes resistance with motion. The Vibra Sense Click uses digital output over interrupt dedicated pin INT to communicate to the host MCU over a mikroBUS™ socket. In addition, this Click board™ features EN, an enable pin that lets you turn off the outputs of the 801S sensor. For a visual presentation of shock detection, this Click board™ features a VIBRA LED that will light
according to the vibration and the potentiometer-set threshold. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
Features overview
Development board
Nucleo 32 with STM32F031K6 MCU board provides an affordable and flexible platform for experimenting with STM32 microcontrollers in 32-pin packages. Featuring Arduino™ Nano connectivity, it allows easy expansion with specialized shields, while being mbed-enabled for seamless integration with online resources. The
board includes an on-board ST-LINK/V2-1 debugger/programmer, supporting USB reenumeration with three interfaces: Virtual Com port, mass storage, and debug port. It offers a flexible power supply through either USB VBUS or an external source. Additionally, it includes three LEDs (LD1 for USB communication, LD2 for power,
and LD3 as a user LED) and a reset push button. The STM32 Nucleo-32 board is supported by various Integrated Development Environments (IDEs) such as IAR™, Keil®, and GCC-based IDEs like AC6 SW4STM32, making it a versatile tool for developers.

* # Description
* This is a example which demonstrates the use of Vibra sense Click board.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Configuring clicks and log objects.
*
* ## Application Task
* It detects vibrations and enables PWM and writes log according to them.
