Sensors for Arduino

Sensors list for Arduino

To make a useful Arduino (any other microcontroller) project you will sometimes need one or more sensors. Even the human body also has five sensors (senses), which are the eye, nose (smell), ear, tongue, and skin (touch). Through these senses, we give the data to our mind and our mind takes action according to real-world …

Digital Decoder and its application in digital circuits

Unlike encoder which converts its 2N input lines into N digits binary number according to input line which is on logic high, digital decoder decodes that encoded N digit binary number and turns an output line high out of its 2N output lines corresponding to that binary number. It is also a combinational circuit and …

Digital Encoder and its application

Suppose you have a lot of sensors connected in your house and you want to control them with a microcontroller. But the problem here is that microcontroller have only few inputs and outputs. The solution for this problem is giving unique IDs (address) to all sensor. Let you have 3 sensors and you have not …

Shift register applications and IC part numbers

Register in digital electronics stores binary numbers. It is a collection of flip-flops which stores digital data as binary numbers. One flip-flop can store one bit data. In shift registers always ‘D’ flip- flop is used. A shift register, as name suggests, shifts data (numbers) which is stored in flip-flops at every clock pulse. It …

Counter and its application in digital electronics

Counter is a very important device for electronics. It is used in many electronics circuits. A digital counter basically counts clock pulses applied to its clock pin. We can use it with display to visually see the digital pulse count. Digital counter with sensor is used to, for example count how many times sensor triggered. …

Demultiplexer applications in digital electronics

Introduction Demultiplexer has one input and more than one output. It is totally opposite to the multiplexers. It has also selector line to select the output line. Let’s say a demultiplexer have one input and 4 output then it will have two select line to select the which output pin should connect to input pin. …

Multiplexer in digital electronics

Multiplexers and demultiplexers are combinational circuit. It is most used combinational circuit in digital electronics. Suppose you have more than one inputs and you have to select data stream from different inputs at different time intervals then you need a multiplexer. You can think it as you have more than one sensor connected in let …

What is the arithmetic logic unit in digital electronics?

Arithmetic logic unit is the very important unit inside a microcontroller or microprocessor. This is called the heart of any processor. As the name suggests, this digital device will perform arithmetic operations like addition or subtraction and logical operation like logical AND, OR or not. Now because this is a digital device so it will …

Latches and Flip Flops

Latches and flip flops are memory device. It can store previous values. There are two types of digital circuit, sequential and combinational digital circuit. Latches and flip flops are sequential digital circuit. When feedback from output is provided to input that circuit is called sequential circuit and in combinational circuit there is no any feedback …
