Ok i'm trying to use this transistor as a switch. I have the collector hooked to 5 volts the emitter hooked to a noid light and the base hooked to a 555 timer threw a 1k ohm resistor.
I can see the noid light get dim and lite but never turned off. I read 2.3 volts then to 4.8 volts.
Why cant I get a reading all the way to 0 volts? Do I need a bigger resistor in line with the base?
No real purpose behind this just playing around with my bread board trying to figure out how all this stuff works.
If i plug my noid light off the 555 i have lite and no lite.
