You can copy and paste the following code in the Python IDLE. Follow the following simple to be able to write the code in Python language.įirst of all open the Python IDLE. We will be writing the code in Python as it is one of the most programming platform for the Raspberry Pi.

Let us know how to write the code for the Raspberry Pi to control the stepper. Programming the Raspberry PI for Stepper Motor: The 12 volt power supply is connected to the L298 motor controller, the motor controller has on board voltage regulator which converts the 12V to the 5 V so you can connect the Raspberry Pi power pins to the 5V supply from the L298 motor controller as shown in figure above. The connection between the Raspberry Pi and the Stepper motor is shown in the following image.

You have to install this library to let the Raspberry Pi control the Stepper Motor. I have already discussed the installation of the GPIO Python library in the Raspberry PI in my previous posts. Notice that to use the GPIO pins we will only need the GPIO python library and nothing else. The Python script tell tells the Stepper motor when to move and how much to move and it will dos so using the Raspberry GPIO pins. The input pins of the L298 motor controller are connected to the General Purpose Input / Output pins of the Raspberry Pi, the General Purpose Input / Output pins gives the proper signal according to the program written in Python language to control each movement of the Stepper Motor. The block diagram of the Raspberry PI and the Stepper Motor is shown in the following image: Raspberry Pi GPIO Circuit Overview: So it becomes important one know how the Raspberry Pi can be used to control the Stepper Motor to carry out these important applications. Raspberry Pi and Stepper Motor:Īs clear that the stepper motor can be interfaced with any controller you want through the motor controller but the reason for using the Raspberry Pi to control the stepper is its high computational power that makes it suitable for self-learning robots, unmanned vehicles based on the Artificial Intelligence algorithms and those robots utilizing the Image Processing and the computer vision algorithms. The following image clarifies the concept behind the L298 motor controller. The H-Bridge topology is very important in the motor controller applications as it has the capability of controlling the direction of rotation of the motor with the 5 V signaling technique as common in embedded controller. The L298 motor controller has the topology of the H-bridge circuit. This can be shown in the following image.

The L298 motor controller has four input pins which control the motor and its direction, two enable pins for controlling the speed via PWM (Pulse Width Modulation), two ports for connecting the motors, on-board voltage regulator and the power port to which 12 volt power supply is connected. L298 motor controller comes in the modular form that is the IC and all the other components are populated onto the same Printed Circuit Board (PCB) and all you need to do is to connect the motors and the power supply to it via connectors. As can be seen in the above section that the stepper motor works in steps, so the stepper motor finds its application when the motion of the unmanned vehicle needs to be precise that is the movement in the forward, backward, right or left needs to be done by a certain degree.
