[sdiy] breadboard woes

[Elain Klopke]

So I was trying to get a reading on my breadboard to see how much voltage
was lost between the input of three passive low pass filters in series and
the output.

My measurements between ground and:
positive supply: 5.06 V
Output from chip: 2.4 V (was expecting 5 V because digital square wave)
junction of first and second resistor: 2.4 V
junction between second and third resistor: 2.4 V
after third resistor: 2.4 V ....

All resistors measured at 5.07 kOhms. I'm not sure what's going on. Is my
breadboard messed up somehow or am I missing something fundamental about
electronics?
