Welcome to our site! Your CD is not connected to 0V so it cannot do anything. If output current is close to maximum increase the value of C1 accordingly. Why don’t people read the datasheets?? The datasheet for the LM says dztasheet use a 0. I think you are talking about the 0,1uF capacitor which should be connected to pin 5 control? For a better experience, please enable JavaScript in your browser before proceeding. Attached is a proper decoupling circuitry for the NE Thread starter Smonjirez Start date Oct 6, Smonjirez New Member Oct 8, But, it flashes totally randomly and in variating brightness also totally random.

The datasheet for the Cmos Intersil’s ICM shows that an ordinary causes a supply current spike of mA when its output switches. Should I do that? But if you’re talking about another condensator connected to another input or daasheet, could you please modify my circuit and post it? Hey, I’m kinda new to this forum, but I have a question.

Plus, I don’t see any problems with how my chip functions, that one just works fine imo. I think this is what you want? This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

According to the datasheets I followed it isn’t nessecary datasyeet connect pin 5. Got part of the scheme from internet Knight Rider lights for model cars and extended it myself with another additional chip to use 8 LEDs in this “back and forth” configuration.

Did you try to sequence two? If you don’t then the circuit probably will not work properly.

So well, the cascading comes for later. Electro Tech is an online community with datxsheetmembers who enjoy talking about and building electronic circuits, projects and gadgets. Smonjirez New Member Oct 9, The control pin has nothing to do with decoupling. This stays the same when I mount more LEDs to the other ports, it’s not how it’s supposed to be.

Yes that was my first attempt but it failed so hard I switched back to just one chip, but it still behaves very odd.

Does anyone know what I did wrong? I’m currently working on a knight rider scanner.

The datasheet for National’s ordinary the LM shows that it needs two supply bypass capacitors to keep other ICs from crashing when the output switches. I don’t see the important supply bypass capacitors. Well I haven’t ground pin 11 indeed.

Weird 4017 behaviour

The circuit will work alright if you cascade the counters. Click here to register now. Boncuk New Member Oct 6, Media New media New comments Search media.

Smonjirez New Member Oct 6, Hi, that is what audioguru tried to make clear to you.

Can’t find any errors in my configuration. The problem is, I’ve got the timer to work, no problem there, can adjust the pulsing speed with a k potentiometer just mounted a LED to pin 3 with a ohm datashsetno problems there.

How much current are you trying to draw from the pin? Articles Top Articles Search resources.

But, when I connect pin 3 from the timer to pin 14 from the chip and of course the 0V, reset and enable pins to the 0V linethe output is kinda weird. You do have a resistor in series with the LED? Boncuk New Member Oct 9,
