    Stumped on this circuit blinking led with 1 transistor

    Minder, please read this partial reply from 73's de Edd . . . . . . Please read his "entire post too". Very helpful "Your activation with "finger resistive bias" to the base, signifies that all is well with your wiring, you just . . .YET . . . haven't found a transistor with a low enough break...

    Stumped on this circuit blinking led with 1 transistor

    Well 73's de Edd thank you very much for your helpful imput. I will try different NPN transistors as you suggest. Funny they don't go into specifics about the transistor. Also, I had no idea that having batteries in series would make a differance, again nothing specific about that in the...

    Stumped on this circuit blinking led with 1 transistor

    The point is this circuit is supposed to blink on its own with the base not being used. I was just following the video to try it out. I don't care if it has a purpose, but it did give some unanswered questions "the base is floating!" means nothing to me without a layman's explanation. I am a...

    Stumped on this circuit blinking led with 1 transistor

    Hello, I used 12 volts DC the video uses 12 volts too a 9 volt battery and 3 volt AA in series I used my 12 volt power supply

    Stumped on this circuit blinking led with 1 transistor

    Hello All, Hope you can help me in plain easy to understand terms, I am a newbie. Thanks http://www.electronicshobbyprojects.com/basic-circuits/blinking-led-with-single-transistor.html I followed this tutorial and used all the components specified and the led does not blink unless I touch the...

    Learning experience simulating a bad ground on a 2008 dodge charger

    Hello All, I was checking out some youtube videos on electronic issues with cars and found this great site where there was a bad ground on the, left front, parking light/turn signal circuit on a 2008 dodge charger. I reproduced the circuit on a breadboard as a learning experience. I have it...

    Explain why DMM reads 00.0 on negative side of circuit

    This is the best video explanation I ever found Tell me what you think

    Explain why DMM reads 00.0 on negative side of circuit

    I am learning a little and I like to watch hevans1944 Here are some videos that explain things well

    Explain why DMM reads 00.0 on negative side of circuit

    Thanks Dave I will do my best to grasp all this stuff :)

    Explain why DMM reads 00.0 on negative side of circuit

    hello hevans1944 I guess I am a slow learner when it comes to electricity. But my question was not about a short circuit it was about the reading of the resistor on the negative side of the circuit. I took the best pictures I could with the probes showing where I was testing. Sorry if you...

    Explain why DMM reads 00.0 on negative side of circuit

    Ok, I see what you are saying. Thank you very much. :)

    Explain why DMM reads 00.0 on negative side of circuit

    Ok, I understand the short has continuity, but a good reading also has continuity and low ohms. So how do you tell when it is a short just using a dmm. Sorry if I am confused

    Explain why DMM reads 00.0 on negative side of circuit

    What reading would you expect to see if the resistor was shorted?

    Explain why DMM reads 00.0 on negative side of circuit

    So Martin If someone were to hand you this breadboard, with this circuit would you be able to tell them if the circuit would work, using just a DMM wouldent the 00.0 reading confuse you?

    Explain why DMM reads 00.0 on negative side of circuit

    So in my case it would be electrically connected, right? I mean the circuit works when I apply power

    Explain why DMM reads 00.0 on negative side of circuit

    Yes but I don't see "understand" where I have a break. Why is the resistor braking my path?

    Explain why DMM reads 00.0 on negative side of circuit

    Ok so here is where I am confused. Why am I getting a good resistor reading .474 ohms only on one side of the resistor, if the resistor is the bridge to complete the circuit?

    Explain why DMM reads 00.0 on negative side of circuit

    Why do you say it is a dead short? Isn't 00.0 on the ohm setting meaning continuity? Also there is no power going to this breadboard.

    Explain why DMM reads 00.0 on negative side of circuit

    Pretty much please see my new pics. The resistor is hard to see in my new pics but it is in line with the negative leg of the led across the breadboard gap and fed by the small black jumper wire.
