When i use this code and connect a jumper to Enable in the H-bridge on a PWM pin
the motor doesn't work at all
but when i put the capsule on the enable pin to disable the speed control it works fine with the maximum speed
#include <SoftwareSerial.h>
SoftwareSerial HC05(2,3) ;
String data ;
int Data;
int R_Forward = A0;
int R_Backward = A1;
int L_Forward = A3;
int L_Backward = A2;
int Speed_R = 5;
int Speed_L = 6;
int Speed = 180;
void setup() {
Serial.begin (9600) ;
HC05.begin (9600) ;
//Right wheel
pinMode (R_Forward,OUTPUT) ;
pinMode (R_Backward,OUTPUT) ;
pinMode (Speed_R , OUTPUT );
//Left wheel
pinMode (L_Forward,OUTPUT) ;
pinMode (L_Backward,OUTPUT) ;
pinMode (Speed_L , OUTPUT );
}
void loop() {
if (HC05.available()>0) {
data = HC05.readString();
Data = data.toInt();
// Serial.println (Data);
}
switch (Data)
{
case 1:
Forward ();
Serial.println("Forward");
break;
case 2:
Right ();
// Left ();
Serial.println("Left");
break;
}
void Forward(){
analogWrite (Speed_R,Speed);
digitalWrite (R_Forward,HIGH) ;
digitalWrite (R_Backward,LOW) ;
digitalWrite (L_Forward,HIGH) ;
digitalWrite (L_Backward,LOW) ;
analogWrite (Speed_R,Speed);

}
