Tinkercad: tutorial dc motor with rotary encoder

This video tutorial on Tinkercad shows how to control a dc motor with arduino and L293D reading a rotary encoder connected to the interrupts pin 2 and 3 of arduino.
With the code in the examples you are going to stop the motor when the encoder reads a definde value of hits.

Hello, Great tutorial, is it possible to turn right, then stop and turn left in the same sequence using if condition?

[@MauroAlfieri77]

Yes!! It is possibile.

[@OS-kd3vm]

Can someone explain me why we couldnt set the Encoder A and B to INPUT? Because normally if the Motor is rotating the Encoder should send an Impulse, i mean thats how it works in real... Has Tinkercad a problem with the DC Motors or something?

[@MauroAlfieri77]

Hello,
from minute 5:53 to minute 6:20 I set pin 2 and 3 in INPUT mode, digitalWrite: HIGT and attachInterrupt CHANGE.
Which sketch are you referring to?

[@MrPrasanth12]

If i am using 2 Dc motors and I need to run one in clockwise and another one in Anti-clockwise can I know how supposed to be program?

[@MauroAlfieri77]

Yes, you can find many examples in my blog: mauroalfieri.it

[@harirohithnp4139]

Where can i get this code

[@MauroAlfieri77]

Hi @harirohithnp4139 you can find the code on my Blog: mauroalfieri.it under section "Corso Tinkercad".

[@General12578]

How do you make it go faster

[@MauroAlfieri77]

Simply, increase the PWM value in the analogWrite.

[@najmiaz-zahraferyputri653]

Hello, i try it but it didn't work for me, the motor didn't move. Do you know what happen..?

[@MauroAlfieri77]

Hi Najmi, check the correct connection between motor and driver L293D and between driver and Arduino Uno

[@demka9773]

Why you do analog write to digital pin motorA(5)? Is it related to driver working principle?

[@MauroAlfieri77]

Because pins 3,5,6,9,10,11 of Arduino Uno are able of sending PWM signals. This special function allows you to use the analogWrite command.

@@MauroAlfieri77 thank you

When I try to run the code on your TinkerCAD, its full of errors and wont run

[@MauroAlfieri77]

Hi Andrew, what kind of errors do you receive?

[@andrewwhite310]

@@MauroAlfieri77 I'll have to try it again, I may have found a bug with tinkercad and there may be no errors in your code. I think tinkercad has an issue running a different circuit following a previous circuit being left open after it had been running previously. I opened yours to compare it to mine because mine code wasn't working, which is when I ran into errors with your code. I then found someone else's tinkercad a little bit later and the first time I tried running theirs, it also errored out again. I simply tried running the code a second time, and the errors all disappeared.

[@MauroAlfieri77]

@@andrewwhite310 it would be a very interesting bug to document and report to the platform.
Is my code working for you now?

[@GenesisZeroTechnology]

variable long lastEncoderValue = 0; //is never used

[@MauroAlfieri77]

Correct, you can remove it.

[@sidharthm1579]

Bro is this a stepper motor

[@MauroAlfieri77]

No, this in a DC motor with an integrated encoder

[@SoloBrainCell]

How I can download the same software you are using ?

[@MauroAlfieri77]

Hello, the software is online, you can find tinkercad in Google.
