R - 2R Ladder Digital to Analog Converter

R-2R ladder DAC is the most widely used circuit for converting the digital signal into the analog signal. For implementing R-2R DAC we require only two different values of resistors, one is R and other is 2R.

Universal Logic Gates NAND and NOR

With the help of NAND and NOR gate, we can implement any logical realisation that's why these gates are known as universal gates.

Getting Started With Arduino Uno

Arduino Uno is an open-source hardware development board designed by Arduino company and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
