## Article

This is my first instructable. Not looking for sympathy, just saying this may not be the most ‘polished’ ible you’ve read.

I ran across Blynk on Kickstarter after the campaign had closed. I thought it sounded cool and quickly downloaded the app to my iPhone…where it sat…staring at me…for months.

Today, I decided to do something about it. I love the Arduino platform and have done many projects using various shapes and sizes (moteino anyone?) I had an Uno lying around looking lonely. I pulled an ethernet shield off of another project…stole a cat5 cable from another system in my shop and cobbled together what follows.

What I thought may take an hour or several, turned out to really only take a few minutes. I hope you all find this to be at least somewhat helpful.

For this little project, I used the following:

Arduino Uno

Arduino Ethernet Shield

Mini Breadboard

Green LED

Red LED

2 100 Ohm resistors

A few jumper wires

Cat5 cable for ethernet

USB cable for power/programming

## **Step 2: Wire It Up**

I ran jumpers from ground, pin 9 and pin 6 to the breadboard and placed the resistor(s) between the + (anode) and the signal jumper.

## **Step 3: Code It .. Sort Of**

Create a new project in the Blynk app on your phone (download it first of course) . Add a button and set it from the default of "push" to switch. The set the output pin ( I used pin 9 for the red LED ). Add a slider and associate it to your pin. Make sure it's a PWM pin ( I used pin 6 for the green LED ) I turned off the "send values on release only" setting as I wanted it to dim in real time.

Click on the nut icon for project settings and send yourself the auth token.
