I have a Sony tv remote, but not an audio remote. I do not know the brand Visio.

I have recently decoded my Mitsubishi heat pump remote. It sent 180 bits of data for every key press.

I will see what I get with a Sony tv and let you know how I get on.

Which remote are you having problems with?

Hi All

I have been also working with Mitsubishi heat pump and my article here may help you all.

http://wiki.crowe.co.nz/Mitsubishi%20Heat%20Pump.ashx

If you are using Ken Sherrifs library you need to increase the buffer size since the Mitsubishi (well my one) sends 180 bits of data which needs 180 bytes of data to store it.

But hopefully the article will help.

I have a c# application that can read a signal - decode it and then rebuild it.

I need to continue my article and maybe able to do this over the coming weekend but hopefully it helps someone here.

Hi, I am trying to do the same, I've tried but I have not managed to crack the code on the remote IR, would you care to comment as you did please?
a greeting

Hi

I have just wrote some details on the Mistubishi IR remote bit patterns on my Wiki at http://wiki.crowe.co.nz/Mitsubishi%20Heat%20Pump.ashx

Hope it helps

Thanks for posting this! I am thinking of trying to automate our Mitsubishi heat pump with an Arduino as well! Did you ever go through and try to decode the full IR protocol (e.g. what the individual codes are for each parameter)?

How are you using the Arduino?

Hi Nate

I have started to document what I have done in order to decode the bit pattern from the Heat Pump - still a work in progress but should be of value to you.

See http://wiki.crowe.co.nz/Mitsubishi%20Heat%20Pump.ashx

I Paul

I am going to write up what I have done but it will probably take a little while to go this done. In the mean time feel free to PM me if you have any questions.

Hi

I have spent quite a bit of time lately trying to decode a Mitsubishi Heat Pump remote control IR signals so I can simulate via Arduino + c# app.

I finally have it mastered and I can now turn the unit on/off, control the mode, control the temperature, control the fan speed, control the swing so pretty much everything I want.

The next problem for me is that I would like to make a small unit (minimal Arduino) that will site in front of the heat pump (about 6 meters in front).

The problem's I see are:

1) I need power to the device
2) I need to send signals to the device to tell it what to do.

What I would like is to automate this so I can have the system automatically maintain a comfortable temperature based on other temperature sensors I already have.

So I need to send a simple Wifi/Bluetooth/2.4G or 443 Mhz signal.

I guess anyone who does any projects like this runs into the same problems - power and communicating with the unit.

The unit location means I do not want to run cables down the wooden beam as it would detract from the beam and it is in my living area.

My ceiling cavity is not accessible either (well I do  not think it is)

Because of the requirement for some sort of wireless communications I know that batteries is a bad idea, but I need power.

I guess if I run cable for power then I could run a serial cable as well.

So just looking for ideas from people who have had similar projects?  What did you do?

Probably a bit of my conform zone - I was hoping there was a quick and simple method.

55  Using Arduino / Networking, Protocols, and Devices / How to detect loss of ethernet network? on: October 12, 2012, 03:37:53 pm
I have an Ethernet shield and am using the standard Ethernet library.

What is the best way to detect that for example the network is no longer available?

If I pull a cable out of my PC it knows pretty quickly that it is not there any more.

Is there a status I can check for?

otherwise your arduino's voltage regulator might run a little warm, but it should be fine as it has protection in the IC

I have also purchased one of these:
 
LM2596 DC-DC Step Down CC-CV Adjustable Power Supply Module Output DC 1.5V-35V

http://www.ebay.com/itm/LM2596-DC-DC-Step-Down-CC-CV-Adjustable-Power-Supply-Module-Output-DC-1-5V-35V-/250954117473

Not sure if I need it since I am unsure if this is better than the simple Voltage Regulator on the arduino?

Would it be worth putting this inline?

if its not crowbaring the power supply it will be fine, as far as protection you want to throw a diode across the solenoid ( cathode to + side, anode to - side) so it wont spit out back EMF on your power lines causing spikes and noise

Thanks for the info - any ideas on the spec of the diode? or maybe a part # for me to look into?

Hi all

I want to run my Arduino Mega on a single 240v to 12v DC supply that I have.

The 12v DC output is rated at 1a

My circuit will be quite simple:

* Power Arduino Mega - it will run Ethernet, RTC Clock, and a Relay board used to turn on and off the solenoid
* Power a 12v solenoid - seems to pull about 300m-500ma (not sure of the startup current) - see http://nicegear.co.nz/robotics/12v-solenoid-valve-34/

The relay board is from EBAY - see http://www.ebay.com/itm/1-Channel-5V-Relay-Module-for-Arduino-8051-AVR-PIC-DSP-ARM-/180982430549?pt=LH_DefaultDomain_0&hash=item2a2364bb55

Directly wiring up the solenoid to the transformer seems to work fine turning it on an off.

I am planning on just splitting the 12v between the Solenoid and Arduino.

My question is how much of a drain does this put on the Arduino? Could it cause it to lockup while switching on/off?

Should I add any sort of "protection" to the Arduino side of the power supply?  If so what?

Cheers

59  Using Arduino / Installation & Troubleshooting / Re: Arduino Driver - ATMega2560 - Windows 8 RTM on: September 18, 2012, 02:00:34 pm
Thanks for the tip - I right clicked on the Arduino MEGA 2560.inf and selected install and then it installed.

Funny how when I told Windows to go to the Arduino\Drivers folder it did not find anything?

But I am now away under Windows 8 so thank you for the advise.

ps: I have also enabled the unsigned driver option in Windows.

This method does not require new driver files or installation of a test signature.

1. Windows Key + R
2. Enter shutdown.exe /r /o /f /t 00
3. Click the "OK" button
4. System will restart to a "Choose an option" screen
5. Select "Troubleshoot" from "Choose an option" screen
6. Select "Advanced options" from "Troubleshoot" screen
7. Select "Windows Startup Settings" from "Advanced options" screen
8. Click "Restart" button
9. System will restart to "Advanced Boot Options" screen
10. Select "Disable Driver Signature Enforcement"
11. Once the system starts go to Arduino/Drivers folder and right click on the Arduino device you have and select install.

I think you should be good to go then.

Really hoping someone can give me another idea for a driver for AtMega 2560 on Windows 8 RTM
