Hi KrisBlueNZ,
With the LDR Buffer build above, it will provide a range of 0V to 5V range of output to the Arduino?
Also what does CW and CCW stand for? Is it continuous Wave?
On the schematic here, where is VR1 on this Op AMP Diagram? So I can know where to place the Bourns 3296W trimpot.
The goal of my project is to use a fiber optic cable that can take in different spectrums of light and run it into a photo-resistor to provide (Through the diagram) a range of 0-5V...
I would line an analog signal ranging from 0-5V depending on the amount of light on the photo-resistor. I'm using the NTE941M op amp. What do I have to change to create an analog signal ranging from 0-5V based on the schematic I provided?
Hi everyone,
I have a circuit with a photoresitor in it (and an OP amp) that gives out a voltage range of 0-.135V.
Is there anyway I can expand the range of the voltage from 0-.135V to 0-5V to get a more dramatic change in voltage when light hits the photoresistor?
