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.
NOR gate is a digital logic gate, designed for arithmetic and logical operations. This gate is mainly used in applications where there is a need for mathematical calculations. So in calculators, computers and many digital applications use this gate. Here we are going to use 74LS32 IC for demonstration, this chip has 4 OR gates in it. These four gate are connected internally…
AND logic gate is a digital logic gate, designed for arithmetic and logical operations, every electronic student must have studied this gate is his/her career. This gate is mainly used in applications where there is a need for mathematical calculations. So in calculators, computers and manly digital applications use this gate. Here we are going to use IC 74LS09 for…

Thermometers are useful apparatus that have been used for a long time for temperature measurement. In this project, we have made an Arduino based digital thermometer to display the current ambient temperature on a 16x2 LCD unit in real time. It can be deployed in houses, offices, industries, etc., to measure the temperature. We can divide this Arduino…
