SparkFun Blynk Board - ESP8266

Story

What is "Blynk" .... It is a Smart Phone APP that uses either Android or iOS to IoT your projects for remote control. To get things started download the Blynk app off Google Play or Apple itunes.

Part 1

Run the APP and continue to Signup for an account (you will need this for authentication). Click on the "Create New Project" selection to start the process. Name your project and on the Hardware Model choose ESP8266 (there are many other selections including Arduino, Raspberry Pi, etc)

It will create an "Auth Token" which its best to straight away email to your self as you need to paste this into your ESP8266 code later.

Next a blank screen will be shown which confused me at first until I discovered that a "Right Swipe" of the screen brings in the "Widget Box"

In our example we will set it up to control a Servo (5 actually) using an ESP8266.

Simple single ESP8266 Servo Code controlling servo on GPIO15
/*
* This sketch demonstrates how to scan WiFi networks.
* The API is almost the same as with the WiFi Shield library,
* the most obvious difference being the different file you need to include:
*/
#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <Servo.h>

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

Servo servo;
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, "WiFi Name", "Password"); // replace with your WiFi router details
servo.attach(15);
}
BLYNK_WRITE(V15)
{
servo.writeMicroseconds(param.asInt());
}

void loop()

{
Blynk.run();
}
