3 DC Motors,1 Servo, Arduino Uno, HM-10

[wcirvin]

Hi,

I am trying to get 3 bi-directional DC motors to work along with a 180 degree servo. 2 of the DC motors will steer and drive the rc car I am building. These 2 are my main concern at the moment. I am using an HM-10 Bluetooth module and a L298N motor shield (although I suspect I will eventually have to switch to an Adafruit v2, but that’s neither here nor there) I have been able to connect to my bluetooth module for some time now and had it controlling my 180 degree servo before I introduced the motorshield into the equation (because servos can just be straight wired to the arduino and don’t require a motor shield.) Now that I am trying to get the motor shield involved I’m getting nowhere. Can someone pleeeeease help me by posting their code to get one dc motor working and controlled via a button on the blynk app. I know I have it wired correctly and I also know I have bluetooth and a servo good to go. But this rc car is useless if I can’t actually drive it! Here is my code that currently runs 2 servos (although I will be using 1 now.)

#define BLYNK_PRINT Serial
#include <BlynkSimpleSerialBLE.h>
#include <SoftwareSerial.h>
#include <Servo.h>
SoftwareSerial SwSerial(10, 11); // RX, TX

char auth[] = “d651b25ee9394d8fb295690a7317a317”;

Servo servo1;
Servo servo2;

BLYNK_WRITE(V5)
{
servo1.write(param.asInt());
}

BLYNK_WRITE(V6)
{
servo2.write(param.asInt());
}

SoftwareSerial SerialBLE(10, 11); // RX, TX

void setup()
{
// Debug console
Serial.begin(9600);

SerialBLE.begin(9600);
Blynk.begin(SerialBLE, auth);

Serial.println(“Waiting for connections…”);

servo1.attach(5);
servo2.attach(6);
}

void loop()
{
Blynk.run();
}

//end code

Hello,

Firstly, please format all posted code as per the instructions you deleted in order to post here… Please edit your initial post acordingly.

Also a good idea to block out part of your Auth code or someone else will be driving your servos

If this is the first time you hear about Blynk, check out our website www.blynk.cc and come back! As the community is big (and growing), let’s agree on some basic rules. Asking for help Before creating a new topic and asking for help, please check if your question was already answered: Use forum search function You may want to check out: Blynk Documentation Blynk Wiki Blynk Exa…

Secondly, we help people learn about Blynk here, not hand out code on request

That said, there is plenty of examples that others have already posted, I even have one… so I suggest you search this forum for keywords like Car, Rover, DC motor, etc.
