Smonjirez New Member Oct 8, If output current is close to maximum increase the value of C1 accordingly. Thread starter Smonjirez Dayasheet date Oct 6, But, it flashes totally randomly and in variating brightness also totally random.
Did you try to sequence two? 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. This stays the same when I mount more LEDs to the other ports, it’s not how it’s supposed to be.
Boncuk New Member Oct 9, Hi, that is what audioguru tried to make clear to you.

Can’t find any errors in my configuration. Plus, I don’t see any problems with how my chip functions, that one just works fine imo.
Should I do that? Hey, I’m kinda new to this forum, but I have a question.
Well I haven’t ground pin 11 indeed. I’m currently working on a knight rider scanner. Does anyone know what I did wrong?
You do have a resistor in series with the LED? Replacement Transformer Started by ncag Today at 7: Electro Tech is an online community with overmembers who enjoy talking about and building datashedt circuits, projects and gadgets. Forums New posts Search forums.
Click here to register now. 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.

Smonjirez New Member Oct 6, Media New media New comments Search media. Your CD is not connected to 0V so it cannot do anything. I don’t see the important supply bypass capacitors.
I think this is what you want? Potentiometer Questions Started by norbss Yesterday at To participate you need to register. 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.
Boncuk New Member Oct 6, The control pin has nothing to do with decoupling. Articles Top Articles Search resources. Else I still have no idea what to do. Datasheets, Manuals or Parts. The datasheet for the LM says to use a 0.

How much current are you trying to draw from the pin? You must log in or register to reply here. The datasheet for the Cmos Intersil’s ICM shows that an ordinary causes a supply current spike of mA when its output switches.
Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at According to the datasheets I followed it isn’t nessecary to connect pin 5. Yes that was my first attempt but it failed so hard I switched back to just one chip, but it still behaves very odd. But if you’re talking about another condensator connected to another input or something, could you please modify my circuit hfc4017 post it?
Btw, I’m using a 12 – 13,5v accumulator as a powersource. I think you are talking about the 0,1uF capacitor which should be connected to pin 5 hcf401 Why don’t people read the datasheets??
