The purpose of the opamp is to convert photocurrent of photodiode to voltage (Vo) than this Vo , will be amplied using another op-amp
1.The problem here is that i dont know which Op-AMP is suitable to use for the conversion and amplification ? . Initially i used 741 , but it seems to be stucked as it requires V+ and V- as 15V and -15V while arduino only supply voltage arround 0-5V.
2.I want to read the Vo values , than transfer it to arduino for processing . Vo is expected to be much larger than 5V (which is the maximum analog reading of arduino) . So how can i do this ?
