Arduino MKR1000 & Blynk

A simple IoT (Internet of Things) experiment using Arduino/Genuino MKR1000 and Blynk. Watch the video below (click here) to see its action, then follow the instructions to build your own!

1. What You Need 🎁

To build this project, you need the following items:

• 1 Arduino/Genuino MKR1000 board
• 2 LEDs
• 1 Potentiometer
• 1 breadboard
• some jumper wires
• Arduino IDE (download here)
• Blynk mobile app
  • Android (download here)
  • iOS (download here)
• WiFi101 library (read how to install here)
• Blynk library (download here)

2. Setup Blynk App 📱

• Open Blynk app, login then create a new project. Choose device: Arduino MKR1000 with connection type: WiFi. Click Create button & you will receive Blynk Auth Token by email.

• On your project, add 2 button widget & a gauge. Set each widget as the picture below.

  

3. Schematics 🔧🔨

• Connect your parts to Arduino MKR1000 as the following picture:

  

4. Sketch 📋

• First, extract Blynk library then copy it to C:\...\Documents\Arduino\libraries.

• Open Arduino IDE then copy sketch below. Insert your WiFi SSID, WiFi password & Blynk Auth Token. Make sure you have chosen the right option for Board and Port under Tools menu. Upload it!

  #define BLYNK_PRINT SerialUSB
  #include <SPI.h>
  #include <WiFi101.h>
  #include <BlynkSimpleWiFiShield101.h>
  
  char auth[] = "Blynk_Auth_Token";
  char ssid[] = "Your_WiFi_Name";
  char pass[] = "Your_WiFi_Password";
  
  void setup(){
      SerialUSB.begin(9600);
      Blynk.begin(auth, ssid, pass);
  }
  
  void loop(){
      Blynk.run();
  }

5. Have Fun! 😎

• After uploading done, make sure your Arduino MKR1000 & smartphone has a good internet connection. Click play button ▶️ on top right corner of your Blynk project, then you're ready to go! Have fun!
