I too am interested in this project. Have there been any updates? Have you moved the discussion to a different forum?

I made the change. I get this result when pressing the 1(BD) button 4 times.

Code:

My Vizio remote and my Sony remote for my sound system.

Does anyone have a solution to getting more than one code sent by the remote?
6  Topics / Home Automation and Networked Objects / Re: iPhone controlled universal remote on: January 13, 2013, 01:23:33 pm
I'm in the same boat right now. It's all hooked up and I can read the codes. But every time I press the button it seems like a different code is sent.

Ontop of that the Vizio remote shows an unrecognized protocol. Is there a better IR library to use?

The motor uses about 70mA

When I go to radioshack what transistor should I buy?

Okay this is what I ended up doing.

Arduino UNO Rev3 http://www.seeedstudio.com/depot/arduino-uno-rev3-p-694.html?cPath=132_133
Bluetooth Low Energy Shield http://www.seeedstudio.com/depot/bluetooth-low-energy-shield-p-1255.html?cPath=132_134
Grove - Base Shield http://www.seeedstudio.com/depot/grove-base-shield-p-754.html?cPath=132_134
Grove - Cables http://www.seeedstudio.com/depot/grove-universal-4-pin-20cm-cable-5-pcs-pack-p-749.html?cPath=178_179
Grove - Infrared Emitter http://www.seeedstudio.com/depot/grove-infrared-emitter-p-993.html?cPath=139_204
Grove - Infrared Receiver http://www.seeedstudio.com/depot/grove-infrared-receiver-p-994.html?cPath=139_204

The beauty of this setup is that it's all off the shelf parts and shouldn't require any soldering.

I will make an iphone app the communicates via bluetooth and will put it on the store for anyone to use.

Okay I got this idea for a Bluetooth enabled universal remote controlled via an iPhone. From my initial research it looks like I should use an Arduino Leonardo with this shield

Am I on the right track? Any thoughts?

I'll double check. Can you point me to a transistor I could buy at radioshack?

I also added a buzzer so that it beeps when you turn it on per my friends request. I got the diode wired up and all is working fine now.

I have added a corrected version of the snubber diode diagram.
13  Community / Gigs and Collaborations / Re: Tacit Modification for Blind Friend on: December 06, 2012, 02:07:01 pm
I've attached a schematic. I assume this is what I should do?

First the diode is wired backwards creating a short circuit, reverse it. Then test the motor current draw.
Only if the current draw from the motor is around 30ma or less should you wire it directly to a output pin with using a switching transistor. You should first wire it to the arduino 5V pin and then with your multimeter wired in series take a current measurement. Only then if under 30ma or so should you wire it to a arduino pwm digital output pin.

Excellent smiley I believe that's all I needed. And you guys have my code so if anyone wants to make one feel free smiley

Here's some pics for the project

So my next question, if I skip the transistor part how do I wire the diode?
You don't skip the transistor part until you've proven that the motor doesn't draw more than about 30mA when you clamp the output shaft.
With or without the transistor, you wire the diode in parallel with the motor, with the cathode to the positive side.

LOL... I'll get my multimeter and double check.

And will just use a diode as you suggest.

Thanks smiley
