Hi Everyone, First of all, thanks for such a great resource. I have been lurking for a bit and just made an account to ask for help with a little project I am working on. What I am trying to accomplish is a motion sensing device that performs a function when something enters the detection space. To be a bit more specific; I have a 5.5v power source I have a IR sensor that runs on 5.5v and depending on distance of object in its LOS, outputs between .3-3volts (for this use anything that enters will be minimum of 1v output) I have a motor that runs on 5.5v and draws about 300mA while running (Can not find stall amperage) I need to find the correct components to put into all of this and make it work correctly. I have some random Transistors laying around and got one to work, but as a stress test held the circuit closed for 2 minutes and burned it out. I am a novice with identifying Transistors, but even looking around online could not find exactly the ratings for the one I was using (It says 8050 D128). I know this was not the "right" way to do this, but this is what I tried that had success. 5.5v + went to Collector 5.5v + went to IR + terminal 5.5v - went to IR - terminal IR output went to Base Emitter output went to motor + terminal 5.5v - went to motor - terminal I know it was wrong to not use any resistors, but I didnt have anything that worked on hand (i tried a 1k between 5.5v+ and the collector, did not work) This transistor seems to not be reaching full saturation as the output voltage is around 2.5v (but still runs the motor as proof of concept) and when I kept the my hand in the sensor for 2 minutes to run the motor continuously, the transistor became incredibly hot, and was damaged (permanently closed circuit regardless of whats at the base) I tried to include as much information as I could, please let me know if I can provide more information that could be helpful. Thanks!
