DC Motor Control using Arduino

Here we are going to interface a DC motor to Arduino UNO and its speed is controlled. This is done by PWM (Pulse Width Modulation). This feature is enabled in UNO to get variable voltage over constant voltage. The method of PWM is explained here; consider a simple circuit as shown in figure. If the button is pressed if the figure, then the motor will start rotating and it will be in motion until the button ...

Arduino – Control a DC motor with TIP120, potentiometer and multiple power supplies

A quick circuit showing how to control the speed of a DC motor with a potentiometer with your Arduino board. Also shows how to use a TIP120 transistor to allow the Arduino control a larger power supply. Transistors are 3 pin devices, which via the 3rd pin (Base) allow it to control the current passing through the other 2 pins (Collector and Emitter). So for this tutorial I am using the power from the Arduin ...

Control a DC motor with Arduino and L293D chip

This is a quick guide with a bit of extra info (pin configurations etc..) that I’ve learnt along the way on how to use the L293D with the Arduino, showing that we can: A) Use a supplemental power source to power the DC motor B) Use the L293D chip to drive the motor C) Use a switch to change the direction of the motor UPDATE: If you intend to use this for robotics then please check out this page here to get ...

DC Motor Control Using an H-Bridge using arduino

Overview In this tutorial, you'll learn how to control a DC motor's direction using an H-bridge. To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit. There are many different models and brands of H-Bridge. This tutorial uses one of the most basic, a Texas Instruments L293NE or a Texas Instruments SN754410. I ...

DC motors Relays

Let's get the math over right off the bat. There are a LOT of attempts to describe how Ohm's Law works, each one nerdier than the last. Here' one I like. Warning: SFWBN (safe for work but nerdy). V = voltage measured in volts - the difference in electrical potential. I = Current measured in Amps or Amperes - the rate of the flow of electrons. R = Resistance measured in Ohms (Ω) - opposition to the flow of t ...
