Hey Michael , Loved how you made it look so easy but I need help I'm facing a problem.. I have my trig and echo pin connected to A1 and A0 respectively and I replaced the no. in your code to A1 A0, and when I turn on the car the motors dont run and servo motor is also not moving.. please help me out here:(

thank you so much for the help, it was very intresting and emosjonell. this expirience was life changeing. I have many of these robots now wich roams my grochery stores. i'am now a proffesional robot maker. i build robots, hand made. im rich now.

hey please anyone tell this work..? please🙏

[@a.w.aardiansyah9211]

Amazing project ! Just Additional Information... Ask permission Mr. Michael Klements for those of you who are new to assembling, then there is a problem with the speed of the motor.. the solution is: 1. Change the byte value of motorSpeed 2. check the condition of the battery, is it still good or not 3. check the state of the gear motors (dynamo) Thank you for your attention Greetings from Ponorogo, East Java, Indonesia

[@lilianseverinodasilva94]

What do you suggest to use instead of byte?

[@MichaelKlements]

This could be caused by a number of things; the battery can't supply enough power, the shield is faulty, the connections are faulty, the speed gains need to be turned up, the code is getting stuck somewhere (waiting for ultrasonic sensor) etc.

[@MichaelKlements]

Yes you can use an Uno clone board, as long as it has the same pinout as the original Uno it should work with the motor driver shield.

[@vlogwithskr9554]

Sir I made the project for my college. And the car is working very well but one problem is that if the front of the car is empty then the car is still rotating.I checked the code many times, checked the hardware connection and found no problem. I don't understand why my car is not working like yours. Sir Please help me to fix it. I have to show this project to the college very soon. Hope you can help me fix it, thanks 😊

[@MichaelKlements]

The motors are not made equally so there is almost always a side of the car that has more power. You need to adjust the variable motorOffset to account for this. If it is turning left all of the time then you need to increase the offset, if it is turning right then decrease the offset.

[@vlogwithskr9554]

@@MichaelKlements Sir, when the front is empty, the servo motor is still rotating, that means the car is turning instead of going straight even on the empty road. It seems to detect some object in front.

[@GG-sd2dr]

hello Mr. Klements, I tried putting a 3 x 3.7V rechargeable battery with a total of 11.1V but when I added 5V to it giving a total of whopping 16.1V, the Arduino Mega 2560 stopped working. Did I supply too much current? is the 11.1V enough for the 4 motors?

[@MichaelKlements]

I'm not sure how or why you added 5V to it, 11.1V is enough to supply both the motor shield and the Arduino. That said, 16.1V also should not have damaged the Arduino Mega since these can typically handle a supply voltage of up to 20V.

[@techysoham]

Hi Michael, thanks for the project! I did everything and made some changes on my own and the car works good! Just one issue, the servo motor is spinning too fast, so fast that it removes the wiring sometimes. Do you have any idea on how to fix this, like how to slow down the servo?

[@MichaelKlements]

Hi Techysoham, thats great to hear. There are some Arduino libraries that offer servo speed control, the other option would be to create a functional that moves the servo in single single-degree increments with a small delay between each step.

Can we use 18650 li ion battery?

[@MichaelKlements]

You'll need to use 2 to meet the voltage requirements of the shield.

[@ZVEKOfficial]

Mate what batteries do you use to power this thing ? I thing that's the most important aspect of this project (you skipped the part where you install the batteries) since many of us who're trying to get this to run use 9V batteries and that simply isn't the optimal power source

[@MichaelKlements]

Either use 4 x AA batteries in a pack or use a 2 or 3 cell LiPo battery (that's what I've used).

[@ZVEKOfficial]

@@MichaelKlements Yeah well I bought a 4 pack and a 6 pack AA holder. The 4 pack doesn't have enough voltage (1.5 x 4) as the L293D driver has a voltage drop of around 1.8V so the motors spin reaaaallly slowly. Nevermind turning left/right. The 6 pack is also meh to be honest. I think I need to buy a high voltage high capacity LiPo battery like you mentioned to run this at its full potential. Or maybe 2x 18650 Li Ion battery

You'll need to solder the pins in place once they're in the holes so that you get a good electrical connection.

@@MichaelKlements Hi! I've since noticed it only ever turns one direction, regardless of obstacles location. I can reverse the turn direction by changing AF_DCMotor assignments Left to Right, but I can't get it to decide to best turn direction, it only goes same way each time. The servo was incorrectly looking right first, but fixing that didn't fix the problem. I downloaded your Code again in case I accidently changed something that matters, no go. Also played around with the 'int checkDirection()' in curiosity.. Anyway maybe you can suggest an answer if you have time. Thanks from QLD Australia.

[@Shalaby2002]

I have a question about the yellow-capped component labeled "PW" on the motor shield. Additionally, I've developed a car using the same procedure and utilizing two 3.7V batteries each. However, I've encountered two problems: 1- When I unplug the USB, the car stops working. 2- The batteries seem unable to power all four motors to move the car. Initially, the setup worked fine during testing, but these issues arose later on. Could you please provide assistance on how to address these problems? and what specific Batteries and how many of them I need and what volatge.Thanks In adavnce

[@MichaelKlements]

I assume you're talking about the jumper labelled "PWR" - mine is black not yellow. This is jumper that either allows the shield to supply power to the Arduino or disables this feature if the voltage is outside of the Arduino's range. If you're supplying power to the shield only then you need to have a jumper on here to power the Arduino as well. Using 3.7V batteries, you would need them to be connected in series and ensure that they can supply enough current to drive the motors.

[@Shalaby2002]

@@MichaelKlements Thank you for your response. Yeah Man , you got me correctly. I was referring to the yellow PWR in my case 😂. From your comment, I gather that I need two batteries, providing approximately 7.2V and 1200mA. In this scenario, I simply keep the PWR turned off as it's. COZ I'm afraid of messing things up

[@MichaelKlements]

You need a supply voltage of at least 4.5V, so either one 7.4V battery or two 3.7V batteries in series would work. If the jumper isn't on then you need to provide the Arduino with it's own power source as well.

A 9V battery isn't able to provide enough current to drive four motors. It works when powered by USB as well as it is supplementing the shortfall. You need to use a better battery pack.

[@PlexusSkIllz]

Hi Michael, it would be a great help if you tell me what I'm doing wrong here.

I've seen some other people have the same problem as I. I made sure that my connections are correct so what might be the problem. Thank you very much.
