Hi all,
I have been attempting to build a circuit on breadboard that responds to a change in light level. For this circuit, I am using a light to voltage converter (The TSL12S-LF) which successfully outputs up to 5 Volts into a comparator (The LM311N).
The problem is that no matter what the differences are between the voltages on both inputs to the comparator, there is nothing coming out.
I have drawn a relevant diagram to help explain what I am talking about.
I have nothing connected to "strobe" and "balance"
Any ideas why Vout is always zero? Have I completely misunderstood a concept? I'd love to know!
Much appreciated,
Ben
