It changes from +5,07 VDC to 0,60 VDC. +5 actually are +5,17, so it means that base voltage swings from -0,1 to -4,57V, relative to +5V. But it does not work, even if I connect the base straight to GND, which gave base -5 V, relative to +5. 2012/4/20 Dave Caroline <dave.thearchiv...@gmail.com>: > a common mistake is to assume collector is the middle pin like the npn > but its the base I checked for the errors in connections at least 4 or 5 times, especially not to mix up collector and emmiter, I knew that the base is in middle, but never found anything. Diode also is soldered correctly (the light stripe on diode's case is on the transistor's side). What else could possibly wrong?
