Pulse detection Mood Lamp

[saleh]

Hi Guys, Im doing my Final Year Project and i have a lot of issues to solve and im stuck. i hope somebody can help me.

Besically, My groupmate and myself have decided to create something called the Pulse detection Mood Lamp. This is how we hope it will work.

We will first detect the pulse of any person using EMANT300 that is connected via USB and we have managed to get the proper pulse's into the VI. Now this is where the problem comes in, we need the output to go to a mood lamp. and we are not sure how to control this. we had a few options , but my supervisor cancelled them out too.one was to use the philips living colours mood lamp and using their RF-Remote to control the mood lamp which is too complicated.Next was to use PIC 16F628(A) but i have got no idea how to convert this .hex file into a .vi file. so im wondering what i can do to convert this pulses's into Coloured lights. I was thinking of Using LED as the output.but again im not too sure how to go about doing that. the colours will change depending on the pulse. so basically when a person inserts his/her finger into the pulse detector, the colour of the Led/Lamp should change according to their pulse. all i need to do now is to figure out what to use as my output and how to programme it.

This sounds like a fun project.

First, a .hex file has nothing to do with a .vi file.  The .vi file is the file that contains your LabVIEW program.  The .hex file is probably some sort of binary file that is meaningful to the PIC.  There is no way to "convert" the .hex file to the VI.

What do you mean by using an LED as an output?

What kind of interface does this colored mood lamp have?  You mentioned an RF remote.  Does it have any other way of controlling it such as an analog input (either voltage or current) or a serial interface?  What options were you thinking of and why did your professor cancel them?

Yea, its a pretty fun project.The RF controlled remote controls the Philips mood lamp, we were actually sticking to that. but for that we have to create a Radio frequency generator circuit to control the mood lamp. this circuit would be connected to the VI. We have a device to actually capture what frequency the remote give out but what we don't know is whether this frequency is encrypted or not. or will it be possible to transmit this frequency from the circuit we create to the mood lamp. we might eventually ernd up doing this. they have not really cancelled it out. they said it can get pretty complicated. so if we are sticking to the RF generator. ll need to know how to create a RF generator circuit which can be connected to the VI.

An easier way would be to open the RF control, and simulate key presses by
connecting the buttons with solid state relias. Or, if the buttons connect
an input to 5V, use a ttl output. That would be much easier and way cheaper
than simulating an RF signal.

I agree with Wiebe.  Modifying the remote control is a much better way to control your lamp.  I have done that with an IR remote control for a video tape recorder and it has worked for years.

The LEDs should also be fairly straightforward.  The EMANT300  specifications indicate that the digital outputs can drive 20 mA which is sufficient for standard LEDs.

The EMANT300 LV drivers can use some updating.  For example the EMANT300 Find All.vi can create havoc if you have several (non-EMANT300) devices connected.  It changes the emulated serial port settings before checking ID but does not change them back afterwards if the device is not an EMANT300. I have rewritten it to eliminate that problem.  What version of LV are you using?
