Didn't I say I was following the book example? So, the schematic is the same. The only thing missing is the input voltage at the base which is 3.3V.You so not show a schematic for the circuit (post #59) on your breadboard with a BC547B transistor with a 5.02mA collector current and a bunch of series resistors at the base with a total of 50.78k. The voltage feeding the resistors is unknown and how can the beta of the BC547B be only 100?
