You may object that this will provide Cojnter which are on when the output is low, and off when the outputs are high, which is confusing.

In that case, invert the signals going to your LEDs. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. For breadboards, use a cap for each IC. It’s always the simple things.

Whenever I press the clock button I get all of the leds on except maybe one or two, with some flashing during the button press. TTL works much better pulling loads down. Okay I wired 7,9, and 10 together and then connected them to a 1K resistor to 5V.

Get into the habit now. Since you already need one section of aand there are 6 gates per IC, you simply go. I added a 0. Then I used a pullup resistor for the clear couunter.

couner Without this buffering, your switch should not work on a button push, only on a release. So your outputs should be connected like. Post as a guest Name.

I’m still getting the same effect. I’d reduce that down to something in the nF to 1uF range.

Finally, you should not count on TTL outputs driving high, as you have shown. I have added a debounce circuit, but still to avail.

As further issues arise I see myself stuck once more with a dysfunctional circuit. That’s probably causing as much trouble as no debounce was. Sign up using Facebook. So your outputs should be connected like simulate this circuit — Schematic created using CircuitLab You may object that this will couner LEDs which are on when the output is low, and off when the outputs are high, which is confusing. For a circuit board with a ground plane, the usual guideline is at least one cap per 5 ICs. Email Required, but never shown.

I switched the LEDs around and connected their input to 5V and their ground to the output pins. Also, have you added a 0. You can often get away with less, but as you’ve just learned, insufficient decoupling can have weird symptoms.
