Learn Digital Clock Basics [PyroEDU]

Posted May 2, 2013 by Chris

Time for another new lesson on PyroEDU’s current course: Introduction To Digital Electronics course and it’s called Clocks and Oscillators. Here is what this week’s lesson is all about:

The heart and soul of any digital system is the main clock signal. It drives every single flip-flop that is inside of the system and therefore it is the most important signal. In this lesson we will learn how to use a 555 timer as a clock signal generator and we will also look at using crystal oscillators to generate clock signals.

    send some useful videos abt clock propeller

    it’s mostly been that some kinds of resistors are not ac resistance and are dc?

  3. Chris Says:


    AC or DC does not matter. The resistor will still limit the amount of current that can flow through a circuit.

  4. jesmion Says:

    we got disappointed when ac resistor got blown or scorch at ac 260 voltage?

  5. Chris Says:

    Probably because you exceeded the maximum power that the resistor could handle. Most resistors are limited to 1/4, 1/2 or 1 Watt at most. Special resistors can handle much more power, but they are not often seen in designs.
