I have 2 C945 transistors and 2 BR9014 transistors that I would like to use for a h bridge. I've been trying all day unsuccessfully. When I do a basic circuit like that: http://forum.arduino.cc/index.php/topic,52984.0.html
, and use a C945 alone, it does work accordingly to my script, the motor spins for one second, stops, and does it over and over again. But with a BR9014, it just keeps spinning forever, without stopping. How's that? I really don't understand and have been trying all day.
I first tried the H bridge, then I tested all the transistors I had, checked each one of them to know if they were NPN or PNP. I finally selected these 4. I'm just wondering if it's normal that it keeps spinning with the BR9014... But I've already tried the H bridge and it doesn't work anyway.
What am I doing wrong?
