DIY iPhone controlled electronics

In this Instructable I'll show how to control your stuff with your phone and the arduino board. I've controlled everything from smoke machines too christmas light's with this program.




Video:

sorry the video is kinda odd because my camera is trying to adjusting for the light difference.

Step 1 The parts

The parts

-NPN transistor

-Iphone/ Android(Using Iphone)

- The TouchOSC app (awesome app)

-Arduino 5v (any type)

-some wire

-Soldering iron

-Breadboard (optional but recommended)

- A Mac or PC

-Some sort of remote or low power button (anything that runs on AA,AAA batteries is usually fine)

-If you want to control a appliance look at the last step fore more info.

and thats it!

Sometimes this happens, it's just a glitch in processing youll have too download the oscp5 libary manually from here :http://www.sojamo.de/libraries/oscP5/#installation and set it up like the following [sketchbook DIR]/libraries/oscP5/library/oscP5.jar
You don't need to remove the jar from the folder.

I am definitely going to do this once i repair my iPods screen :D

[rklemka]

By the way, does anyone knows good samples ar tutorial using TouchOSC and Microsoft Visual c++?

[TheTeslaWarrior]

hey, i get ""osp5" does not exist." error on controlproccesing.pde

[rklemka]

Did you inserted libraary as sead in:

2. You will need to download the oscP5 library for processing
Go here and download the library. Extract the files and move the folder oscP5 to this directory {C:\Users\[your user name]\Documents\Processing\libraries\[put the folder here]}
?
And after inserting you need to turn off all processing windows and rerun it :)

[rklemka]

hi, nice article, can you readd pde filoes? Because i can only download tem files, and when I rename them to pde, aplication is incomplete:
import processing.serial.*;
import oscP5.*;
import netP5.*;
OscP5 oscP5;
int alphaValue;
Serial arduinoPort;


float v_push1 = 0.0f;
float v_push2 = 0.0f;
float v_push3 = 0.0f;
float v_push4 = 0.0f;

void setup() {
size(320,440);
frameRate(25);
arduinoPort = new Serial(this, "COM1", 9600);//change to the serial port arduino is on
/* start oscP5, listening for incoming messages at port 8000 */
oscP5 = new OscP5(this,8000);

}

void oscEvent(OscMessage theOscMessage) {

String addr = theOscMessage.addrPattern();
float val = theOscMessage.get(0).floatValue();

if(addr.equals("/1/push1")) { v_push1 = val; }
else if(addr.equals("/1/push2")) { v_push2 = val; }
else if(addr.equals("/1/push3")) { v_push3 = val; }
else if(addr.equals("/1/push4")) { v_push4 = val; }
}

void draw() {
background(0);

// fader5 + push 1-4 outlines
fill(0);
stroke(0, 196, 168);

rect(17,21,287,55);
rect(17,369,60,50);
rect(92,369,60,50);
rect(168,369,60,50);
rect(244,369,60,50);

// fader5 + push 1-4 fills
fill(0, 196, 168);
if(v_push1 == 1.0f) rect(22,374,50,40);
if(v_push2 == 1.0f) rect(97,374,50,40);
if(v_push3 == 1.0f) rect(173,374,50,40);
if(v_push4 == 1.0f) rect(249,374,50,40);

if(v_push1 == 1.0f) arduinoPort.write("U");
if(v_push1 == 0.0f) arduinoPort.write("u");
if(v_push2 == 1.0f) arduinoPort.write("D");
if(v_push2 == 0.0f) arduinoPort.write("d");
if(v_push3 == 1.0f) arduinoPort.write("L");
if(v_push3 == 0.0f) arduinoPort.write("l");
if(v_push4 == 1.0f) arduinoPort.write("R");
if(v_push4 == 0.0f) arduinoPort.write("r");




as I see the rest is missing.

[mman1506]

It should run if it does not. Try this

import processing.serial.*;
import oscP5.*;
import netP5.*;
OscP5 oscP5;
int alphaValue;
Serial arduinoPort;


float v_push1 = 0.0f;
float v_push2 = 0.0f;
float v_push3 = 0.0f;
float v_push4 = 0.0f;

void setup() {
size(320,440);
frameRate(25);
arduinoPort = new Serial(this, "COM1", 9600);//change to the serial port arduino is on
/* start oscP5, listening for incoming messages at port 8000 */
oscP5 = new OscP5(this,8000);

}

void oscEvent(OscMessage theOscMessage) {

String addr = theOscMessage.addrPattern();
float val = theOscMessage.get(0).floatValue();

if(addr.equals("/1/push1")) { v_push1 = val; }
else if(addr.equals("/1/push2")) { v_push2 = val; }
else if(addr.equals("/1/push3")) { v_push3 = val; }
else if(addr.equals("/1/push4")) { v_push4 = val; }
}

void draw() {
background(0);

// fader5 + push 1-4 outlines
fill(0);
stroke(0, 196, 168);

rect(17,21,287,55);
rect(17,369,60,50);
rect(92,369,60,50);
rect(168,369,60,50);
rect(244,369,60,50);

// fader5 + push 1-4 fills
fill(0, 196, 168);
if(v_push1 == 1.0f) rect(22,374,50,40);
if(v_push2 == 1.0f) rect(97,374,50,40);
if(v_push3 == 1.0f) rect(173,374,50,40);
if(v_push4 == 1.0f) rect(249,374,50,40);

if(v_push1 == 1.0f) arduinoPort.write("U");
if(v_push1 == 0.0f) arduinoPort.write("u");
if(v_push2 == 1.0f) arduinoPort.write("D");
if(v_push2 == 0.0f) arduinoPort.write("d");
if(v_push3 == 1.0f) arduinoPort.write("L");
if(v_push3 == 0.0f) arduinoPort.write("l");
if(v_push4 == 1.0f) arduinoPort.write("R");
if(v_push4 == 0.0f) arduinoPort.write("r");
}

if you don't want a pc in the middle, check out the ardumote app (http://bit.ly/nGBvjD). VERY easy to use, cheaper, and doesn't require a PC... it sends messages directly to the ethernet shield over WiFi.

[flyinfinn]

Hey,
Great writeup! Does this require a PC connection to the phone? I mean, after everything is configured and done, do you still need the PC on to operate the arduino?

Thanks alot!
Shane

[xshi26]

You can control your arduino without a pc in the middle with the Ardumote app: here is a link to it on the app store: http://bit.ly/nGBvjD

found this video of it on youtube: http://www.youtube.com/watch?v=lX-VxmEOtIM

[mman1506]

It does need a connection to the pc as the computer changes the osc commands into serial command which the arduino reads

[jamilm9]

Is there a way this could be controlled using a arduino ethernet shield and not have to use a computer? Thanks.

[mman1506]

This may help http://recotana.com/recotanablog/closet . i need to buy one of those ethernet sheilds some time

[carjo3000]

What is the range of the communication? Does it only work within the same wifi network? I was just thinking it would be cool to control something in my house from across town :)

[mman1506]

sorry for the late answer. No you do not need to be on the same wifi network but it requires some setup before it will work. I'll try to summarize the process.

1.go to your router configuration and forward the ports 8000 and 9000
2. if you do not have a static ip already (you likely have a dynamic IP) go to http://www.dyndns.com/services/dns/dyndns/ and install it and copy down the ip it gives you
3.In touchOSC input the ip you found in the last step in the network configuration setting for hostname
4. run it normally

[carjo3000]

Thanks, it works great! Awesome instructable. Now I'm working on making an IR remote so I can control my TV from my iphone :)

[marselsipod]

This may sound noobish, but how does the phone send the command to the arduino? Do you have a wifi shield for it or something? sorry im tired XD

[mman1506]

The phone send an Osc signal through you're wifi network and processing then picks up this signal and send serial data through the USB cable and into the arduino. The arduino then responds with the appropriate output.

[TheTeslaWarrior]

cool, thanks.
ive been playing around with the program, how would i get it to just do a digital output? i don't have transistors on me.

[TheTeslaWarrior]

never mind, got it. thanks for great instructable!

[mman1506]

Thank you. Awesome tesla coil I've always wanted to make one

[TheTeslaWarrior]

they are fun :)

[mman1506]

It already is. You can light an led. All the transistor is an electrically controlled switch.

[Jamo_G]

Sweeet! I totally want to try this when I get some time =D

[computer_gui]

The robot is a TI EvalBot right?

[mman1506]

wow that was quick! I would give you a patch but I'm not a pro,so a virtual high five will have to do.
