This way, they aren't just following instructions. Once the board is complete, the user is encouraged to watch these videos before actually creating the circuit on the board. Each block have a dedicated tutorial video that offers circuit diagrams, theory, and lab sections. THIS IS A FULL TUTORIAL ON THE 74LS93! My electronic learning boards have many functions that are broken down into blocks. Once you understand this tutorial, you can interface this circuit with a 74LS47 BCD-7-segment dispay decoder IC, and a common-anode 7-segment display. This will help us to make a clap on/off circuit on the learning board. The first output (A) toggles each time a pulse triggers the clock. This chip is very useful, as we are not only going to use it to count in binary, but we are also going to use it as a toggler. The purpose of this video is to teach you how to create the circuit, determine output frequency based on external resistor-capacitor values, and how to connect it all on a breadboard. This video demonstrates the 74LS93 Decade Counter IC. Hi all!!! This is my fifth of many electronic block tutorials for my upcoming electronics learning board.
