Technically called as Intel MCS-51 Architecture, the 8051 microcontroller series was developed by Intel in the year 1980 and were very popular in the 80’s (still are popular). 8051 Microcontroller has many features like Serial Communication, Timers, Interrupts, etc. and hence many students and beginners start their work on the concept of Microcontrollers with 8051 Microcontroller (although this trend seems to be changed with the introduction of Arduino). Even though 8051 Microcontroller might seem a little bit out of fashion, we feel that it is one of the best platforms to get started with Microcontrollers, Embedded Systems and Programming (both C and Assembly)....

It has 131 instructions, most of which execute in a single clock cycle....

Below charger automatically shut off the charging process when battery attains full charge. This prevents the deep charge of the battery. If the battery voltage is below the 12V, then circuit automatically charges the battery. Automatic 12v Battery Charger Circuit Diagram This automatic battery charger circuit is mainly involves two sections – power supply section and load comparison section. The main supply voltage 230V, 50Hz is connected to the primary winding of the center tapped transformer to step down the voltage to 15-0-15V....

What is pH? We often associate pH ranges and values with chemical reactions as a chemical can be highly effective at a specific pH value. For example, Water corrosion and softening are controlled by adjusting the pH values. But what is pH? pH is short for potential of Hydrogen. pH is a measure of Hydrogen Ion activity in a liquid. To understand more clearly about pH and its measurement, you need to first understand the molecular structure of Water....

Air pressure: When you check for an airbrush kit, you know that the airbrush itself is the only thing that will help you to complete the makeup. However, until the airbrush is equipped with powerful pressure, it will not be able to provide the ultimate performance that you are looking for. So make sure that you check the air pressure to improve the performance. With more air pressure, it can become easier for you to get a satisfactory ultimate result....

Choosing the right motherboard depends on a lot of factors and can seem to be a mammoth task. To ease things, we have listed the top features that you need to look for when selecting an expensive motherboard. CPU Socket: The CPU socket is the one that links the motherboard to the processor and allows it to connect to several other devices. As it is an important factor when looking at a motherboard, you need to go for the one that is absolutely compatible with your processor....

Introduction A DIAC is much similar to the transistor so more strictly it is called as a transistor than a thyristor. However, it has an important role in Triac triggering and other thryristor based circuits. Several gate triggering circuits use this device for achieving greater triggering stability and noise immunity. The DIAC stands for the DIode AC switch. It is a two terminal bidirectional switching device. These terminals are not named as anode and cathode in case of normal diode....

There, I have made a small perf board for ESP8266 WiFi Module in order to insert it in the breadboard, you could call it a Breadboard Adapter. Even though this perf board served the purpose of using the ESP8266 on a Breadboard, I still had to connect the level converter resistors, push button to reset the module separately. So, instead of making a PCB for breadboard adapter, I have decided to make a PCB for the ESP8266 WiFi Module with all the required components like connectors for power, GPIO Pins and communication (RX and TX), slide switch for selecting Programming Mode or Normal Mode, Push button for Reset, headers to insert the ESP8266 WiFi Module and the level converter resistors for the RX Pin of the Module....

Why do we need to learn ESP32 Pinout? ESP32 based boards come in a variety of shapes and sizes and pinout of each board is different to other. Also, not all pins of the ESP32 Microcontroller SoC will be available on a development board as some pins might be permanently tied to a dedicated function. One such case is the Flash Memory. We know that all ESP32 boards come with 4 MB of Flash Memory to store the programs....

Biometric Attendance System Circuit Principle: The main aim of this circuit is to take the attendance and display when requested. Finger print identification is based on the fact that no two persons will have the same finger print in this world. This is because of the peculiar genetic code of DNA in each person. Finger print module differentiates between two fingers based on the ridges and valleys on finger print. When the finger print is given it stores the points where there are changes in the direction of ridges and valleys using some algorithms....
