i want to connect a phtotransistor to a pic to receiver a pulsed input from a transmitter. Is this connection right??
what i want is for output to pic to be high when light comes into the pic
what resistance value do i need to set?? i have added a picture of what i am trying to explain.
will i need other components to achieve this??
i am meant to set a resistor value that sets the output to the PIC as >2.8v for a high and <0.4v for a low.
