I have a pulse sensor(ppg) and i am trying to connect it to an analog pin so that i can store the pulse values, but i am having trouble with this. So, my question would be how do i connect the pulse sensor to the the psoc board and what are the components to be included so that i can see some values when i read of the analog pin.

If detection of the peak value of the analog pulse is what you  need, than look into Cypress Application Note AN60321:

It will guide you how to capture peak amplitude of pulses (code provided). All you need then is to digitize it with ADC.

Not clear what are you up to. Please post your project (File-> Create workspace bundle-> minimal)  and/or sensor type/specs to have better response.
