Hardware Overview
How does it work?
Vibro Motor 2 Click is based on the VZ43FC1B5640007L, a compact Eccentric Rotating Mass (ERM) motor that generates vibration/haptic feedback from Vybronics. This motor contains a small eccentric weight on its rotor, producing a vibration effect while rotating it. The VZ43FC1B5640007L draws a typical 100mA while creating a sizable vibration force of 0.91G and makes an excellent choice for applications requiring crisp haptic feedback and low power consumption. This Click board™ also uses the
DMG3420U N-channel MOSFET to drive the ERM motor since the MCU cannot provide enough power for the motor driving. The PWM signal drives the gate of the MOSFET, routed to the PWM pin of the mikroBUS™ socket. The PWM signal toggles the MOSFET gate with pulses of a certain width. As a result, the current through the motor is varied depending on the pulse width of the PWM signal, which directly affects the speed of the motor, effectively controlling the vibration force that way. The circuit also contains a protection
diode, which protects the transistor from the reverse voltage since the motor represents an inductive load. Turning off its current can produce a kickback voltage that can damage the transistor. This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Application Output
1. Application Output - In Debug mode, the 'Application Output' window enables real-time data monitoring, offering direct insight into execution results. Ensure proper data display by configuring the environment correctly using the provided tutorial.

2. UART Terminal - Use the UART Terminal to monitor data transmission via a USB to UART converter, allowing direct communication between the Click board™ and your development system. Configure the baud rate and other serial settings according to your project's requirements to ensure proper functionality. For step-by-step setup instructions, refer to the provided tutorial.

3. Plot Output - The Plot feature offers a powerful way to visualize real-time sensor data, enabling trend analysis, debugging, and comparison of multiple data points. To set it up correctly, follow the provided tutorial, which includes a step-by-step example of using the Plot feature to display Click board™ readings. To use the Plot feature in your code, use the function: plot(*insert_graph_name*, variable_name);. This is a general format, and it is up to the user to replace 'insert_graph_name' with the actual graph name and 'variable_name' with the parameter to be displayed.
