Story

Blynk

Blynk is an IOT platform useful for making projects connected to the Internet and accessible from a phone or mobile device.

Setup

Download it to your device. Click "New Project"

You may have to sign up/log in. My username and password were the same as my Arduino account. This may or may not be the same for you.

Set the board to "Arduino MKR1000." (Blynk does not yet have an Arduino MKR WiFi 1010 option.) Set the connection type to WiFi. Set the name to what you want. Here is a screenshot of what mine looks like in setup.

1 / 8 • My Blynk setup

The emailed authentication token

After you are done with the setup above, upload the code at the bottom of the page to your Arduino MKR WiFi 1010. Open the Serial monitor. After about 15-20 seconds of load time, you should see something like this:

The successful output

Be In the Blynk app, on your new project, press the Play button at the top of the screen. You should now be able to turn the LED from your device now. If not, make sure the LED is connected to GND and D2, the button on your phone is connected to Digital 2 (D2.) Also, try switching the LED, it might be broken, try switching the wires, they might be broken

Code

Basic LED control

/*
 * Starting Blynk code.
 * This code will connect to the Blynk project
 * Circuit: LED connected to digital pin 2, and a 220 ohm resistor to GND
 * Blynk project setup: Button widget (swipe right to left, select button,tap  * button while code is paused (play button at top,) select PIN, then select   * D2)
 * When you press the button, the LED should turn on
 */


#define BLYNK_PRINT Serial // debug output

#include <SPI.h>                  // necessary libraries
#include <WiFiNINA.h>
#include <BlynkSimpleWiFiNINA.h>

char auth = "Your auth token (emailed to you when you create a project)";
char ssid = "Your network SSID";
char pass = "Your network password"

void setup(){
  Serial.begin(9600); // debug output (Serial monitor)
  Blynk.begin(auth, ssid, pass);
}

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