Control a DC Motor using the L9110S driver and a Rotary Encoder with an Arduino - Tutorial

Connect a DC motor to an Arduino with the help of the L9110S motor driver and control the speed/direction with a Rotary Encoder.

Thanks for covering two modules in one video. Very informative.

Once again, a nice clearly explained video ... and a very useful schematic on your website... thanks!

3:27 So, a 1uF capacitor is fine for this motor. But how does this requirement change vs motor size?

Is there a formula, or a rule of thumb? I want to get a slightly bigger motor.

I have a project where i am using a fan to blow a table wind turbine and my team would like to track the rpms from the dc motor. i bought the items you have in this video minus the breadboard power supply. i have a 9v power supply as well as a 9v plug for the arduino can this tutorial work for experiment since we don't want to power our motor but instead see the rotations from the rotor using the encoder?

Awesome, thanks for sharing. Gonna buy that motor driver and power supply. Isn't just too few 5V output? Just wondering if I would connect a bigger motor.

And also I don't know what cables buy to connect to the motor driver pins and to the motor.

Thanks again!

Thank you, but im afraid i do mot understsnd the code in the isr part. Why are there no curly brackets? I just dont get the up bit

[wojciechpvb]

coold - can it also control the stepmotor speed ?  for constant rotation - not in 3d printer ?

, it is possible to use the threadmill motor to a threewheeler bike and do we have a throttles that fit to

[AmritaSingh-cnkp]

do you know the same control of dc motor using rotary encoder via labview instead of arduino?

[carlocolella]

Hi, it's possible to add a display 16x2 so i can see the value on display, so I'll make things portable.
Can you help me to integrate the code?

[JCPrototypes]

can you add a limit switch to this code?

[doktordinkel]

Changing the direction of the motor dosen't work. :/

[stumpy]

I came to this video thinking that it was going to be a tutorial on closed loop control of a dc motor using the encoder. A decent basic tutorial but a vague title....

[ynzeselders]

I thought that pwm goes from 0 to 255, and not 20 to 200. Or am I wrong.

[alex-ul]

how much voltage can i give to driver?
