Hello everybody. I have question about light measurement. I have project where I need to measurement light signal using Led sensor. I need to get light voltage of the output signal between 0 V and 3.3 V. So I chose this interval because I will use ADC converter which to have atmega32, so I don't use more voltage interval because I would like to protect controller input from high voltage signal. So I using LM358 operational amplifier and when I simulation with multisim it's working think but when I connect in a real environment is not work and I don't know why is not work. Someone know about this and can help me.
