I have a 2N3904 NPN transistor. I'm feeding the base 5V. the transistor turns on just fine and it shorts the collector and emitter. However, when I turn my meter on volts, I read around 1- 1.5 volts across E and C. I am using this transistor in a project as a sinking output. Why am I reading this voltage and can I get rid of it?
I'm controlling the transistor with an arduino. Im writing HIGH for 4 seconds, then LOW for 4 seconds. I'm only showing 1.5v across the E and C when the arduino writes LOW!! What is going on??
Here's some more info:
