Hope this article has helped you to better understand how to incorporate DC motors into your electronics projects! Leave a comment below if you have any questions.
A traditional BDC motor controller circuit is an H-bridge. This is an electronic circuit with four open/close switches that supply positive and negative voltage by turns.
Connect the potentiometer to the positive or negative terminal of the power supply. One end of the wire must be connected to either outside pin/prong of the potentiometer.
And note that the fly-back diodes are not integrated within the IC. Therefore, we may include them in the wiring diagram later on. If not placed, you can still have everything running just as fine. As long as, your motor’s load is moderate. As it goes up, the IC will start heating up.
Digital control is used to create square wave. This pattern can vary voltages between full on i.e. 5V and full off i.e. 0V. The duration of on time i.e. when the the signal is present is known as pulse width. PWM waves for the different duty cycles are shown in the figure below.
This page will show step by step the relationship between speed, torque and drive voltage of a DC motor, and how to control it.
It is illustrated in the figure below. By diverting the current, the flux produced is reduced. Hence the speed can be increased above the normal speed.
A DC motor is a device that converts electrical energy into mechanical energy. Today, you find DC motors in many devices we rely on every day such as home and office appliances, automobiles, access control systems, and toys.
In this configuration the On time will depend on the resistor R1, the left side of the potentiometer and the capacitor C1, while the Off time will depend on the capacitor C1 and the right side of the potentiometer.
So as shown in above figure, for clockwise rotation 2A should be high and 1A should be low. Similarly for anti clockwise 1A should be high and 2A should be low.
Time to do the wiring. You can remove the potentiometer to the circuit from Project 2 and replace it with the ultrasonic distance sensor. I am copying here the complete instructions so that you don't have to jump back and forth between the two articles.
As you’ve seen in the DC_MOTOR.h file, the provided APIs do all the basic functionalities that you may need from a motor driver library.
PWM is a method through which we can generate variable voltage by turning on and off the power that’s going to the electronic device at a fast rate.
After inserting the components we need to create the board outline and start arranging the components. The two capacitors should be placed as near as possible to the 555 Timer, while the other components can be placed wherever we want, but still in a logical arrangement according to the circuit schematic.
