About the Code
In this part, we delve into the Arduino code concerning the stepper motor, detailing the operation of the system and the utilization of its built-in functions. Firstly, we incorporate a library in order to utilize its pre-existing functions. After that, we develop an item, especially a stepper, and indicate the specific pins utilized.
Pins 8, 9, 10, and 11 are allocated in a digital format. In the initialization of both the stepper and Arduino, we use the setRpm function to establish the motor’s RPM. RPM stands for revolutions per minute and is used to indicate the rotational speed of the motor in terms of how many times it turns in one minute. As an example, we selected 12 as the starting point, but it can be adjusted to suit your preference.
Within the loop function, we make use of a predetermined function to rotate the stepper motor in a clockwise direction to a specific angle. Following that, there is a waiting period before rotating the stepper motor counterclockwise to a set angle. We are confident that this explanation effectively explains the functioning of the code.
