Stepper 15 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 15 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 85/100%, all the way to the last sequence of the same movement routine of 360-degree angle with a step speed of 85/100%. Results are sent to the USART 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.
