my target is detecting a laser generated with 1k frequency using a solar cell, i'm using this idea which is using a band pass filter on the solar cell to block the dc sun light and let me detect the laser, the problem is that i'm completely lost for how i would implement this in a circuit
i've calculated the RLC band pass filter to have 3kohm, .22h and .1uf, which is not bad to start with
the solar panel i'm using is Mini Solar Panel 6V/250mA
but as i'm inexperienced in this field i'm kinda lost, so please either gimme answers or simple schematic
bunch of questions : q1- is the filter going to remove the dc volt coming from the sun and only leaves me with analog signal of 1k frequency ? aka if the sun will gimme 5v and the laser effect will be 20mv then will the filter o/p be +-20mv square/sin wave ? q2- i'm using microcontroller to read this input so how much current would that produce if i'm using the following schem.., do i need a resistor to limit the current and how would it affect the wave
