Arduino Step Motor Control

Use the analog input with the help potentiometer to control the delay in between each steps of the stepper motor.

Arduino step motor control.

Int val 0. Arduino code description in this section of the tutorial stepper motor speed control using arduino i am going to elaborate you about the arduino source. A stepper motor or a step motor is a brushless synchronous motor which divides a full rotation into a number of steps. We connect the 5v and ground from to uno to the sensor and as a precaution use a breadboard power supply to power the stepper motor since it can use more power and we don t want to damage the power supply of the uno.

When user access webpage of phpoc wifi shield from a web browser on smartphone or pc a websocket connection will be created between arduino and web browser. As shown in the fritzing diagram an external power source can be connected to power the motors. Pin 8 11 are controlling the stepper motor and pin 6 in receiving the ir information. A stepper motor also known as step motor or stepping motor belongs to the brushless dc electric motors with a specificity of dividing a full rotation into a number of equal steps or we better call them equal angles the motor s axis position can be controlled to move and hold at these angle without having a feedback sensor and also due to its high torque capacity this kind of motors could maintain stable the motor axis on hold when it carries a heavy charge.

In the case of stepper motors we can easily control them with the stepper library and there is no need to code each step. Controlling a step motor by rotating a plate on web. Stepper motor is a type of brushless dc motor that converts electrical pulses into distinct mechanical movements i e. The stepper motor used here is a rusty old epoch 5 wires stepper motor which is a unipolar stepper.

For a stepper motor the 4 terminal pins on the h bridge should connect to the 4 leads of the motor. Stepper motor control using arduino is a simple project where a bipolar stepper motor is controlled using arduino uno. The 4 logic pins will then connect to the arduino 8 9 10 and 11 in this tutorial. Arduino stepper motor.

Unlike a brushless dc motor which rotates continuously when a fixed dc voltage is applied to it a step motor rotates in discrete step angles. While the arduino is a convenient and simple platform its library support is what makes it one of the best platforms most modules on the market are compatible via arduino libraries. Include stepper h include the header file change this to the number of steps on your motor define steps 32 create an instance of the stepper class using the steps and pins stepper stepper steps 8 10 9 11. L298 motor controller manipulates the arduino s commands and starts to control the speed of the stepper motor.

Shorter the delay in between each steps faster the stepper motor runs and vice versa. If you are new to arduino you can get started with arduino tutorials for newbie. The shaft of a stepper motor rotates in discrete steps.
