    Hello,

    I found this post in the "completed projects" forum.
    As it says it is for completeled projects.

    Now I moved it here and made it visible to the others.

    Please can you explain more what you are trying to do in normal english in stead of sms lanquage.

    Bertus

    i want to do a project in spo2..the main idea is to measure the amount of oxygen present in blood.. idea i got till now is that,blood contain two sections ,the oxy haemoglobin and the deoxy haemoglobin.ok
    ir led and red led is driven in a frequency that only one is on at a time..as i said early the oxy haemoglobin absorbs more ir and the normal red. also the deoxy haemoglobin absords more red light than ir..so there will be a difference in absorption ..
    i did some circuits found in net..but i couldnt go forward with that..
    thz :D

    Are you aware there is a Shift key on your keyboard?

    The nearest translation I can come up with is you are attempting to make a Blood Oxygen Meter aka SpO_2 meter.

    You were instructed that this was possible with an IR LED and a Red LED. What are you using for a receiver?

    Please post schematic(s) of what you have so far, and use spell check, and if able, use closer to correct English spelling, punctuation, and grammar.

    Grammar and syntax are the rules of proper use of the medium called language. If you use the medium correctly, you will get appropriate results faster and people will be willing to share a conversation with you.
    Here in AAC we are lenient and understanding when the language barrier is concerned, but if you can use the medium correctly, you have no reason not to.

    Try to compare it with driving a car backwards to get to your destination.

    I can only speak for myself.

    When I view an inquiry for help that needlessly has such poor grammar and spelling, I usually won't bother to post a reply.

    If the original poster won't make the effort to at least be mostly correct in their spelling/grammar and have shown to have put forth some effort in researching their project, then why should I expend the effort to do so for them?

    There are many members who do not write/speak English as their native language; however many of them are better writers than those who are native English speakers/writers. I tend to make much more of an effort to help those people solve their dilemmas, as they are obviously making more of an effort to communicate in my native language, and doing a very good job of it.
