Stepper 19 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

}The application task represents an example that demonstrates the use of the Stepper 19 Click board with which the user can sequentially move the motor. The first part of the sequence executes the clockwise/counterclockwise motor movement for an angle of 90 degrees with a step speed of 50%, all the way to the last sequence of the same movement routine of 360 degree angle with a step speed of 90%. Results are being sent to the UART Terminal, where you can track their changes.

}This Click board can be interfaced and monitored in two ways:
- Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
- UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.
The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
