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

@@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.

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

@MichaelKlements4 ай бұрын
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.

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
@MichaelKlements5 ай бұрын
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.
@Shalaby20025 ай бұрын
@@MichaelKlements Thank you for your response. Yeah Man , you got me correctly. I was referring to the yellow PWR in my case 😂.

@MichaelKlements5 ай бұрын
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.

However I would like to understand the difference between calling a function following a void command such as "void stopMove() and the call to distance=getDistance() where the getDistance code starts with the statement "int getDistance()" why isn't getDistance also a void statement? cheers.

Hi Kerrie, There are two different types of functions, ones starting with void just carry out the code in the function and ones that start with int (or String, char, Boolean etc.) are functions that return an a variable or “answer” of that type. void stopMove just tells the motors to stop. Where int getDistance returns the distance measured to the object as an int variable type. Hope that helps make it clear

THe servo moves from 0 to 90 to 180. Then the rover goes backwards till specific distance. But it never turn around. It always goes forwards and backwards. I have used your ocde and modified the tie daelys for some lines but it doesnt seem to turn at all. And yes I have tested the rover in spaces whereleft is more than space on the right etc.. What can I do ? I would really appreciate the help. All the rover turn setting are as such. If Turn left... right motors turn FORWARD, Left motors turn backward...vice versa for Turn Right. I do not know what to do. Please help me.
@MichaelKlements Жыл бұрын
There is not steering mechanism on the car, so to turn left the right wheels run forward and the left wheels run backwards, if the motor speeds are set correctly then the car will rotate on the spot (it shouldn't move forwards or backwards while turning). It sounds like your motor speeds have been adjusted incorrectly, so one side is probably overpowering the other side.
