A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. We are using internal ADC of Arduino to make Digital Voltmeter … [Read more...] about Arduino DC Digital Voltmeter

Introduction to PLC Ladder Programming
We have already discussed the introduction to programmable logic controllers. Please go through it before reading this. In this article, we will give you a brief introduction to programming PLC using the ladder diagram. Programs for microprocessor-based systems have to be loaded into them in Machine code, that is in a sequence of binary code numbers to represent the program … [Read more...] about Introduction to PLC Ladder Programming
Types of ROM | PROM, EPROM, EEPROM, Flash EPROM & Mask ROM
What is ROM? ROM stands for Read-only Memory. It is a type of memory that does not lose its contents when the power is turned off. For this reason, ROM is also called non-volatile memory. Because ROMs are deployed in such a wide variety of applications, there are different types of ROMs suited to different applications across the industry. Different Types of … [Read more...] about Types of ROM | PROM, EPROM, EEPROM, Flash EPROM & Mask ROM
Controlling a Servo Motor with Arduino
A servomotor is also defined as a rotary actuator that allows for very fine control of angular positions. This article explains controlling a servo motor with Arduino in detail. Many servos are widely available and quite cheap. Servos can drive a great amount of current. This means that you wouldn't be able to use more than one or two on your Arduino board without using an … [Read more...] about Controlling a Servo Motor with Arduino
