Add the following snippet to your HTML:. Project tutorial by ambhatt. Along with this, the applied voltage to motor is also measured to see the motor speed at different applied voltage. Finely, after noting down all the values, the observation table is prepared for pulse width duty cycle , applied voltage and motor speed in RPM.

The given project demonstrates above example. It applies PWM to DC motor to vary its speed from min to max and max to min continuously and also measures following parameters.

These parameters are displayed on 16x4 LCD. It is very easy to vary speed of DC motor using arduino. Arduino can generate PWM on its analog output pin and when it is applied to DC motor, its speed varies. So it is very simple and easy task. When motor completes 1 revolution, the sensor generates 1 pulse and such pulses are calculated by arduino to calculate RPM. So let us see how this is done.

Lets start with circuit diagram first, followed by its descriptions and operation. Internal photo transistor is pulled up by resistor R4. The collector output of transistor is connected to digital pin 7 or arduino. RW pin is connected to ground. Some time delay is provided to allow motor to attain full speed. Thus when motor rotates one full revolution, the slot passes through sensor gap.

Due the slot in the wheel the IR light falls on photo transistor. So transistor conducts and generates negative pulse in collector output. Thus each rotation of motor produces pulse.

To measure the frequency of this pulse first the ON time is measured then OFF time is measured and from these frequency is calculated as. Thus the given project varies the speed of DC motor and also measures it accurately. So one can note down motor speed in RPM at different voltage and pulse width in observation table for further needs. Please log in or sign up to comment. Project tutorial by mohitmehlawat.

This is a model circuit that can control the speed and the direction of a dc motor without the h-bridge it's an alternative to h-bridge. An inexpensive project that I put together to set the RPM of a treadmill motor at five preset speeds. Project tutorial by PracticeMakesBetter. The DC motor controlling library is provided to control all types of DC motors especially for industrial motion control. Project in progress by ahmed soliman.

## Speed and Direction Control of DC Motor using Arduino

The LD quadruple half-H drivers chip allows us to drive 2 motors in both directions, with two PWM outputs from the Arduino we can easily control the speed as well as the direction of rotation of one DC motor. Watch a demonstration video. For this tutorial we will be using our basic DC Hobby Motor but this tutorial can be applied to just about any DC Motor out there that falls within the peak voltage and current specifications of the H-Bridge we are using. I hope that some of you might answer my questions below, thanks. The motor is controlled using a h-bridge. However, make sure to plug the Arduino back into the I am newbie and I have encountered with some problems. In this tutorial, you will use the l H-Bridge chip.

If you connect these two leads directly to a battery, the motor will rotate. H-bridges are used in many different applications, one of the most common being to control motors in robots. You can use discrete transistors to make this circuit, but for this tutorial, we will be using the L H-Bridge IC. Its current rating is 2A for each motor. The pinouts for the L are shown below.

Add the following snippet to your HTML:. Project tutorial by ambhatt. Along with this, the applied voltage to motor is also measured to see the motor speed at different applied voltage.

The desired speed is set using a potentiometer. In this assembly, green jumper wire is connected from the center pin of the potentiometer to the Arduino A0 port.
