1. What You Need 🎁

To build this project, you will need the following items:

  • 1 Arduino MKR1000 board
  • 2 LEDs
  • 1 potentiometer
  • 1 breadboard
  • Some jumper wires
  • Blynk mobile app

2. Set Up Blynk App 📱

  • Open Blynk app, login then create a new project. Choose device: Arduino MKR1000 with connection type: WiFi. Click Create button and you will receive Blynk Auth Token by email.
  • On your project, add 2 button widget and a gauge. Set each widget as the picture below.


3. Schematics 🔧🔨

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



#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(){
    Blynk.begin(auth, ssid, pass);

void loop(){;
