Kinda problem :D

[facepwner]

Hi guys im new to this forum but i write here because i seek help. Since some time i builded my self a robot (easy one) nothing very special 2 motors servo and IR sensor for a distance and for a controller im using arduino UNO. OK got it ? Now to the problem ... when i run my first test program i saw something terrible for my eyes servo is runing the code perfectly but that is not the terrible part the motors are not doing anything NOTHING not at all but when i made a program to test the motors alone (with no code for servo) they are acting well and now im STUNED please guys give me some idea to catch

I forgot to say that im using this schematic :

and that code :

Code: [Select]

#include <Servo.h>
Servo microServo;
int motor1APin = 4;
int motor2APin = 5;
int motor1ENPin = 9;
int motor3APin = 6;
int motor4APin = 7;
int motor2ENPin = 10;
int servoPin=11;
void setup() {
pinMode(motor1APin, OUTPUT);
pinMode(motor2APin, OUTPUT);
pinMode(motor1ENPin, OUTPUT);
pinMode(motor3APin, OUTPUT);
pinMode(motor4APin, OUTPUT);
pinMode(motor2ENPin, OUTPUT);
microServo.attach(servoPin);
}
void loop() {
microServo.write(0);
analogWrite(motor1ENPin, 250);
digitalWrite(motor1APin, HIGH);
digitalWrite(motor2APin, LOW);
analogWrite(motor2ENPin, 250);
digitalWrite(motor3APin, LOW);
digitalWrite(motor4APin, HIGH);
delay(3000);
analogWrite(motor1ENPin, 0);
digitalWrite(motor1APin, LOW);
digitalWrite(motor2APin, LOW);
analogWrite(motor2ENPin, 0);
digitalWrite(motor3APin, LOW);
digitalWrite(motor4APin, LOW);
delay(2000);
microServo.write(90);
analogWrite(motor1ENPin, 250);
digitalWrite(motor1APin, LOW);
digitalWrite(motor2APin, HIGH);
analogWrite(motor2ENPin, 250);
digitalWrite(motor3APin, HIGH);
digitalWrite(motor4APin, LOW);
delay(3000);
analogWrite(motor1ENPin, 0);
digitalWrite(motor1APin, LOW);
digitalWrite(motor2APin, LOW);
analogWrite(motor2ENPin, 0);
digitalWrite(motor3APin, LOW);
digitalWrite(motor4APin, LOW);
delay(2000);
microServo.write(180);
}

Hi,

I forgot to say that im using this schematic :

Could you post a real schematic instead?

[facepwner]

You mean a picture of the bredboard ?

[Soeren]

No, a schematic, like this...


A picture of a breadboard (or a drawing of same), is not very helpful, as we have to "draw" a mental schematic from it, to see what's going on.

Save us from such head ache/waste of time and the quality of answers will rise exponentially

oh its a bit hard for me i have never done so hard schematic but i will try my best ...

[Soeren]

Hi,

You don't need to draw the Arduino - just assign the 8 wires with direction (although I guess they're all out from the arduino (to the rest of the circuiit).
Just get the pin numbers for the L293D correct as you have connected it - shouldn't be all that hard

ugh i tryed something but no idea how to do it ... 

[facepwner]

I think i found a clue now i saw that the individual battery for the servo isnt powering it at all and when i try to power the all parts 2 motors and servo i moves the servo only i made few tests with commands by deleting all the part of the servo and adding 1 line after every test and the motors stop runing at that line :

Code: [Select]

myServo.attach(servoPin); i think its all the powering ..
