Topic: TWO ROBOT CONTROLS (Read 646 times) previous topic - next topic


I want to control two robots at the same time but I couldn't write the codes, can you help?

I have two HC-05 modules with Master-Slave connection and another HC-06.

There is not a problem with Bluetooth connections, it is connecting to each other.

I used Arduino nano.

I am just waiting for your help in writing master-slave codes.

The single run codes are as I wrote below.

#include <SoftwareSerial.h>
SoftwareSerial mySerial(11,12); //Tx,Rx

const int in1 = 9;
const int in2 = 8;
const int in3 = 7;
const int in4 = 6;
const int e1 = 10;
const int e2 = 5;
int data;

void setup() {
  pinMode(in1, OUTPUT);
  pinMode(in2, OUTPUT);
  pinMode(in3, OUTPUT);
  pinMode(in4, OUTPUT);
  pinMode(e1, OUTPUT);
  pinMode(e2, OUTPUT);

void loop()

if(data == 'f')
      digitalWrite(in1, HIGH);
      digitalWrite(in2, LOW);
      digitalWrite(in3, HIGH);
      digitalWrite(in4, LOW);

if(data == 's')
      digitalWrite(in1, LOW);
      digitalWrite(in2, LOW);
      digitalWrite(in3, LOW);
      digitalWrite(in4, LOW);

It will help you get the best out of the forum in the future.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
