With the help of our 2-channel BDC motor controllers, users can control robots remotely via a wireless communication module. Our team provided electronic design and embedded software development for the project.
And now after knowing the ARR value, we can plug that into the FPWM equation and solve for PSC to find the approximate Prescaler value for the timer to get an FPWM that is as close as possible to the pre-defined value by the user.
As with Project 2, the 9V batteries depict the motor battery power supply. The black module in the middle of the breadboard depicts the L298N motor driver module with the connections as described earlier.
The other classifications are typical of almost any electrical motor’s controller. Let’s briefly go over them through the example of a brushed DC motor controller.
For example, if you touch the base with your finger it could cause current into the base and the motor will rotate. This is not mandatory but it is good to include to reduce chances of accidental starting of the DC motor. The DC motor is connected as load at the collector.
In this article, we’d like to share our own experience in the design and implementation of a brush DC motor controller. You’ll also learn about challenges you can meet if you decide to build it yourself.
But here we look at just three coils, spaced at 120º. A motor, as we noted in our last session, performs the task of converting electrical energy into mechanical energy. So how does the motor in our illustration do this? Let’s look at what goes on inside.
If this causes many problems, a switch may be installed between these components to shut off the circuit when needed. Once both ends of the wire are connected, the circuit will be ready.
In addition, we’ll share our personal experience and brief you on the design and challenges that you can meet while building your own controller.
After explanation the interfacing of the motors with Arduino, we will show and explain the code for driving and controlling DC motor using PWM. We will show how to use PWM to start the motor from zero to mid-value speed and then maximum speed and then gradually reduce its speed. PWM technique for speed control is not only used for DC motors but also for Stepper Motors.
If you are also looking to control the direction of the motor in addition to controlling the speed, you can check out our alternative project that uses the L293D to control the DC Motor.
You can see how, from a humble beginning, you can start branching out and experimenting with different types of hardware, to gradually reach more interesting configurations.
The working of the program is very simple. Arduino reads the voltage at the analog input pin A0 (slider of the POT). Necessary calculations are done using this reading and the duty cycle is adjusted according to it. The step-by-step working is noted in the program below.
