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.
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.
