The modification requires three additional ICs—74LS04, 74LS260, and CD4075—to provide the correct logic and generate seven outputs. These outputs are linked to seven LEDs, representing the dice faces.

Twenty years ago, if you wanted an LCD for a project, you’d probably end up with something salvaged from a mobile phone or an HD44780 character display. These days, little OLEDs can be had fo… ...

Once again, we’ll be looking at Texas Instruments data sheets: the TI 74ALS04 / 74AS04, the TI 74F04, and the TI 7404 / 74LS04 / 74S04 (as usual, I encourage you to open these data sheets on your ...

This PC based DC motor speed controller circuit allows you to control the speed of a DC motor (in eight levels) from your PC’s parallel port.

Here we use 74LS04 HEX NOT gate chip. Pin diagram of 74LS04 IC is shown below. Components Power supply (5v), 1K resistor (2 pieces), 220Ω resistor, 74LS86 QUAD EX-OR GATE IC, 74LS04 HEX NOT gate ...

NOT gates are simply inverters. They simply invert the input logic for the output. Here we are going to use 74LS04 IC for demonstration. This IC has 6 NOT gates in it. These SIX gate are connected ...

This paper presents an immunity modelling study of a 74LS04 inverter. The purpose of this work is to develop a simple model, using as little measurements as possible, and using only datasheet ...

The other end of the wire should go to pin #5 of the 74LS04 that is a little further up, on the left of the TMS9901. You will notice that pins #5 and #6 are currently not connected to any trace on the ...

The geiger counters put out a 1.ms 3v pulse though, so he first has to run this through a 74Ls04, which spits out the 5V the arduino wants. He’s admittedly no musician, but you can hear in the ...
