Hi all,

I'm currently doing a project on measuring heart rate. I'm using a 8051 and a LCD to display the heart rate. I have used the integrated ADC in the 8051 to display the peak value of the heart beat. Now I do not know how to change the signal coming out of my sensor to digital signal. Any suggestions?

Huh? What am I missing? If the signal out of your sensor is analog, and you bring it into the ADC then it is already converted to digital.
Do you want to convert the sensor signal to digital first?
