    Counter to 15 with a switch (push button)

    I was impatient because I'm going to college on Monday and it did not work with 6V either and I checked the components again and they are all correctly connected. I will try with on college the 5V. When I was putting wires in protoboard I wasn't careful at first and It caused protoboard to...

    Counter to 15 with a switch (push button)

    I'm not that rich I'm a student xD. At faculty they have an osciloscope and an DC power source regulator (I do not know how to call it) but it can give 5V/DC easily can i try that? Can I also try connecting my battery with annother battery 4.5V+1.5 with 6V?

    Counter to 15 with a switch (push button)

    I bought all the the components for the schematic except two electrolyt capacitors. I switched them with two ordinary capacitors of same value and 0.01uF capacitor can store up to 65 Volts. I have a battery of 4.5V. I have connected everything on schematic and triple checked. It doesn't work I...

    Counter to 15 with a switch (push button)

    I took a look at the graph and saw that using resistor of a value of 10M and a capacitor of 0.1 uF makes time delay around 1.2 sec. I have never even heard of the capacitevly coupled trigger before but I will take a look at what it is. Thank you very much for your help :)

    Counter to 15 with a switch (push button)

    I have added the pullup and and pulldown resistor and as for time delay it's a little over 1s (I hope that is sufficient). I changed the value of R6 to 10M Ohm and C1 to 0.1 uF. Is this how you suggested:

    Counter to 15 with a switch (push button)

    I have managed to make the schematic and it works in MultiSim. I know I know I know I know that MultiSim and Reality are two separate things so what I ask is that if you see some problems in my schematic please point it out. For example if you think something will burn out because I didn't put a...

    Thank you very much for your suggestion. I will post when I make the schematic how it works.

    Counter to 15 with a switch (push button)

    The project that was given to me is: Build a digital circuit that shows the numbers from 1 to 15 (and number 0 too ofcourse) on 4 LED diodes. With a switch change the numbers. Basically the truth table 8421. I was thinking of using a 74LS193 counter and with pressing a switch the numbers were...
