Hi. I thought I knew how to use transistors, but apparently not. I am trying to just get the transistor to behave properly to be used in an H-Bridge. I am trying to check proper operation with LEDs.
I cannot get my TIP31C transistors to work properly. I have stared at the literature and internet diagrams, but I am still a bit confused.
Here is my basic understanding:
1) I have hooked up my load to the emitter (LED + 1k resistor).
2) The collector (middle pin), I hook to the power supply (in this case for the LED 5v, or for my 12v motor, 12v)
2) The signal to turn the NPN transistor on or off with 0v or 5v is sent to the base.
This setup is not working. What am I doing wrong? (Sorry bout the crude diagram)
Thx.
