About this project

Hi! Everyone loves RC car, but sometimes there are some problems like too short range or conflict with another RC car (when use same frequency).

But inspired in BT feature of Arduino 101, I wanted to start this project by turning a broken car to BT controlled with phone inclusive.

1. Setting Blynk App

For a tutorial setting Blynk app with an Arduino 101 using BT see: https://create.arduino.cc/projecthub/nhuberfeely/arduino-101-blynk-bluetooth-tutorial-cb4c5d

2. Setting Circuit

I burned a Genuino 101 testing the L293D :'(

I'm using original NiCd batteries of the RC car.

3. Connecting Car Motors

4. Setting Blynk Project

5. Testing and Fun!

Code

Hello101Arduino
//#define BLYNK_USE_DIRECT_CONNECT

#define BLYNK_PRINT Serial

#include <BlynkSimpleCurieBLE.h>
#include <CurieBLE.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "282...";

BLEPeripheral  blePeripheral;

void setup() {
  Serial.begin(9600);
  delay(1000);

  blePeripheral.setLocalName("Blynk");
  blePeripheral.setDeviceName("Blynk");
  blePeripheral.setAppearance(384);

  Blynk.begin(blePeripheral, auth);

  blePeripheral.begin();

  Serial.println("Waiting for connections...");
}

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