Digital Electronics

Digital Electronics is the counterpart of Analog Electronics and it deals with digital circuits that operate using digital or discreate signals. A typical digital circuit can be designed using basic elements like Transistors, Logic Gates, Flip-Flops or even using complex elements like microcontrollers, microprocessors and other computing chips.  This section consists of a huge collection of basic digital circuits with schematics and detailed explanation, to help you build digital electronic projects. You can also check out the Embedded Electronics section for advanced digital circuits that are designed using microcontrollers and microprocessors.
