hello
I need help to design finger tip heart beat monitor.I try to write the code on micro c.but i can't see the calculated HR result on lcd.
I have a little bit knowledge on pic.please show me a sample code to read a microcontroller.
 

Whaaaaaat? You give us absolutely NO information about your hardware or software, and then you ask us to give you ”code to read a microcontroller?”

Do some work on your own, and then maybe someone will help you.
 

Oh sorry my bad question..
Currently my program is done and the correct out put was display on LCD. The problem is that I use pulse signal as an input to microcontroller that comes from the pulse sensor output. But my teacher need to see the design of sensor with a correct amplifier and filter on protus. I tried by using LDR as light receiver from LED. But I can't get a desired wave

Oh sorry my info less question
Currently my program is done and it display a desired output on LCD. The problem is that I give a 2MHz pulse signal as input to microcontroller that comes from pulse sensor. But my teacher need to see the design of sensor with proper filter and amplifier on protus. I tried using LDR as light receiver from LCD and capacitor and opamp to processed it.but still i can't get a desired output pulse.
 

Hi,

Didn't you ask for code? ... and now for hardware?

Show what you have done so far.
At least ideas, hand drawn sketches and diagrams and flow chart, trials, fails..

We are here to solve errors, not to give solutions.
