Introduction: Remote Control 4 Relay With Arduino Via WIFI (touchOSC+Processing)

Hello, i'm not english speaking so please understand my mistakes.

Mine was just an idea, i was curious, i googled some hours but there were a problem: i didn't found a pre-made script :)

I started from a script found on a website, but it was made for one relay, so i remade it.

This instructable is made for 4 relays but you can add how many you want.

Step 1: Materials Needed

Things you need:

• Arduino (I used UNO)
• 4 Relay Module
• Processing, you can download it from HERE if you need the library too here it is

The library should stay in C:\Users\Your Name\Documents\Processing\libraries

• TouchOSC on Itunes

• TouchOSC Editor from Here

• Jumper wires

Step 2: Wire the Relays to the Arduino

Now you have to wire the Arduino and the relay module.

Arduion VCC <-----> Relay module VCC
Arduino GND <-----> Relay module GND
Arduino pin 11 <-----> Relay IN1 Pin
Arduino pin 10 <-----> Relay IN2 Pin

Arduino pin 9 <-----> Relay IN3 Pin

Arduino pin 8 <-----> Relay IN4 Pin

Step 3: Program the Arduino

Download the script and transfer it to your Arduino

Step 4: Setup Processing

Run processing, download and open the script.

Edit the COM port if necessary.

Step 5: Setup TouchOSC

Now we need to setup touchOSC, you can find your host by typing ipconfig on cmd if you are under Windows

Step 6: Upload the TouchOSC Interface

Now with touchOSCeditor open the 4relaycontol.touchosc file and press the Sync button, once pressed on the phone app go to Layout and press Add

Step 7: Test

Run the script on Processing by pressing the "Play" button and connect with your phone.

Press the buttons, if everythig is working the relays will change their status.
