Analogread (), and the detected voltage (0-5V) is mapped to a digital (0-1023) by a number-to- analog conversion technology (ADC) .
If the output of the piezoelectric element exceeds a certain limit value (indicating that the vibration has reached a certain strength) your board will be output through the serial port "detected vibration." "This string to the computer.
You need to open the serial monitor to see the effect. complete the hardware device required for this example An
A real-time application can be used as a standalone task when using an RTOS. Each task has its own operating environment, independent of other tasks in the system or the RTOS scheduler. There can be only one task running at any point in time, which
