help with my project plz

Hi guys.
I have a motor design project. I know there is some transistors into the circuit. I just know about
H-bridge only. Does any other devices participate in it?
Also, I want to verify it works or not with a real car. I am a noob of Arduino .Will there be any suggestion for my project??
PS: I want to make a Infrared carsd

You will have to give us a great deal more information about what you have in mind.

What is an infrared car - one that keeps you nice and warm ?

Sorry I do not have any ideas about my project
infrared remote Control Car

Will there be any suggestion for my project??

Not with an attitude like that there won't.

Reply #2 is illegible on my PC - most of it is just a series of square characters with FFnn inside them.

I suspect I have not missed much.

Fail! :roll_eyes:

I tried googling...Sorry I do not have any ideas about my project

all it came up with is

"sorry, I do not have any ideas about my project."

good luck with your infrared car that sounded like a really neat idea.

I suggest you use google and youtube to find similar projects and study how they were developed. Then come back with the arduino specific questions.

I mean I just know about the H-bridge circuit.Does there any information about the advanced circuit??

Is it bad parenting?

Here's how I did it a couple of years ago....

H-bridge (MotoMama L298 originally but I ditched that crap in favour of Pololu 2130.)

Vishay 38kHz IR sensor

Old TV remote

6V power from AA batteries for motors

Pololu 2120 stepup to give about 7V from 6V to Arduino Vin

Sketch using Ken Shirriff's IR library to read the IR signal and decide what to do.... eg one code means drive both motors forward or another means stop one motor and drive the other etc etc.

"Real" meaning an actual car that you sit in and take down the street?

Here is my code(motor)?
Would you please take a look and give me some advises?

#define EN12 9 //PWMswitch of MRR
#define MD1A 10 //positive
#define MD2A 11 //negative
#define EN34 5 //PWMswicth of MRL
#define MD3A 6  //positive
#define MD4A 7  //negative

#define MRR EN12 //Switch of right side of motor
#define MRR_F MD1A //Forward command pin
#define MRR_B MD2A //Backward command pin
#define MRL EN34 //Switch of left side of motor
#define MRL_F MD3A //Forward command pin
#define MRL_B MD4A //Backward command pin
void setup() {

  pinMode(MRR,OUTPUT);
  pinMode(MRR_F,OUTPUT);
  pinMode(MRR_B,OUTPUT);
  pinMode(MRL,OUTPUT);
  pinMode(MRL_F,OUTPUT);
  pinMode(MRL_B,OUTPUT);
}
void loop() {

if (EN12==HIGH)
{
   if(MD1A==HIGH)
   {
     MD2A==LOW;
   }
      else 
    { 
     MD2A==HIGH;
    }
}     
      else 
    {
       MD1A && MD2A ==LOW;
    }
if(EN34==HIGH)
 {
  if (MD3A==HIGH)
   {
    MD4A==LOW;
   }
  else 
    MD4A==HIGH;
 }
 else MD3A && MD4A ==LOW;
}

I'm sorry for my terrible expression.
''Real'' means that the car is not a virtual car in the internet through simulation
I want to make a simple toy car only

??

MD1A && MD2A ==LOW;
MD3A && MD4A ==LOW;
MD4A==LOW;
MD4A==HIGH;

""MD1A && MD2A ==LOW;"" and ""MD3A && MD4A ==LOW;""
It means that the pins(EN12/EN34) of motor drive(L293D) is not working.
Thus,the circuit would not be opened.

By ""MD4A==LOW;""
When ""MD3A==HIGH;""
The car is moving forward.
MD4A is controlling the backward movement.
So ''''MD4A==LOW'''' when ""MD3A==HIGH""

By
""else
MD4A==HIGH;"" and "EN34==HIGH" condition.
When ""MD3A==LOW""
MD4A is working and car is moving backward.

Sorry for terrible expression.Can I answer your question?

== is not the same as =

What do you think is happening here?
D1A && MD2A ==LOW;
MD3A && MD4A ==LOW;

.

Dude. Don't do the double spaced word thing! It is considered insulting in the Typed English culture!

Use italics instead.

I feel sorry about that
I am not using double spaced word thing purposely.
I just know how to fix that typing problem.

:roll_eyes:

Thank you.

D1A && MD2A ==LOW;
MD3A && MD4A ==LOW;

.

I think there are low voltage across the pins,so MD1A MD2A MD3A MD4A will not work.
