For an overview, DC Motor Control using Arduino is the automation of DC Motor. With the help of this automation, one can create advanced as well as simple voltage control and proportional control of DC Motor. To begin with, let’s discuss the DC Motor control with Arduino, the automation system of DC Motor with L298 H-bridge. The DC Motor Control with Arduino device is a very simple system that allows controlling any type of DC Motor.
The DC Motor control with Arduino consists of an Arduino microcontroller and L298 H-bridge. To control any type of DC motor, the Arduino gets attached to the DC drive via the DC Motor Control using an Arduino shield. When it is turned on, the L298 H-bridge drives the DC motors via timers or code through at least eight pulse width modulation channels.
There are four main steps to drive a DC Motor with Arduino through the PWM signal. The first step is to set up the control circuit. The next step is to program the microcontroller on the Arduino board. The third step is to configure the pins of the DC Motor control using Software Programmer.
The third step is to turn on the DC Motor to be controlled. Then, attach the microcontroller to the DC Motor. The fourth step is to configure the DC Motor speed control. For the fast rotation speed of DC motors, we need a faster terminal voltage control. For slow rotation speed, we need a lower terminal voltage control. For the desired power output, we need a servo motor.
For the RC Coupler, we need to calculate the total power consumed by the circuit; take the total voltage that comes from the battery and the DC Motor; multiply it by the total ampere requirement of your servo motor. Figure 2 shows the value of your battery. In figure 1, the DC Motor and the microcontroller are connected to the VCC terminal. The ground wire is connected to GND.
Step Three: Setting up the PWM Pulse Width Modulation. In the last step, we are going to set up the PWM Pulse Width modulation for the DC Motor control. The PWM pulse width modulation is used as a function of your duty cycle. We can use this as an input to the microcontroller.
Step Four: Testing your DC Motor Control using Arduino. Finally, we are going to use our potentiometer to control the frequency of your PWM. We need to set the value corresponding to your desired duty cycle and connect the potentiometer to your Arduino board. The potentiometer will receive a pulse every time the DC Motor moves.
Step Five: Upload your sketch to your Arduino board. The last thing that you need to do is upload your sketch to your Arduino board. If your serial monitor does not have an LCD connection, you can use a USB connection. You can also use your computer as a visual aid. Draw the DC Motor on the screen and monitor its movement.
The fifth step is to set your desired DC motor speed control values. This can be done by connecting a DC motor to your desired range of frequencies. Start with slow frequencies to test your circuit first. Then once you get comfortable with the speed control values, you can easily increase the frequency.
Step Six: Test your DC Motor Control using PWM. To do this, attach your desired PWM driver to your Arduino board. Connect the output of the PWM to the input of your DC Motor. Then attach the servos to your servo output on your Arduino microcontroller.
Step Seven: Using a servo to control your Arduino using PWM. Your servos should be able to detect a DC signal. Hold down your push button for two seconds and then release the push button. Your servos will now receive a PWM signal that is carrying information on how your DC motor is rotating. Your Arduino will now use this information to control your DC motor using PWM.
Testing your DC Motor Control using these steps is very easy. You can even do this while you are away from your home. What you need to do is connect your servos to your servos, then configure your PWM signal using your servos. You can now power your motor with your batteries. Before you start enjoying the benefits of your motor, make sure that you have followed all the steps in this article. This will ensure that you get the best results every time you run your motor.
