Torque-Speed Control of a Permanent Magnet DC (PMDC) Motor
Torque-speed control of a Permanent Magnet DC (PMDC) motor involves adjusting both the motor’s torque output and its rotational speed. This control is crucial in various applications to ensure the motor’s performance matches the requirements. Achieving torque-speed control involves understanding the motor’s characteristics and utilizing appropriate control techniques. Here’s a detailed explanation of how torque-speed… Continue reading Torque-Speed Control of a Permanent Magnet DC (PMDC) Motor
ARDUINO
Arduino is an open-source hardware and software platform that enables you to create interactive electronic projects. Arduino boards use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits. The… Continue reading ARDUINO
Permanent Magnet DC (PMDC) Motor: Overview
A Permanent Magnet DC (PMDC) motor is a type of electric motor that operates based on the interaction between a magnetic field produced by permanent magnets and the electromagnetic field generated by the flow of current in its windings. PMDC motors are widely used for various applications due to their simplicity, controllability, and efficiency. Here… Continue reading Permanent Magnet DC (PMDC) Motor: Overview
Usage of Trigger (Trig) and Echo Pins in Ultrasonic Sensor HC-SR04
The HC-SR04 ultrasonic sensor is a popular distance measurement device that uses ultrasonic sound waves to determine the distance to an object. It has two main pins: the Trigger (Trig) pin and the Echo (Echo) pin. These pins play a crucial role in generating and measuring the ultrasonic pulses used for distance calculation. 1. Trigger… Continue reading Usage of Trigger (Trig) and Echo Pins in Ultrasonic Sensor HC-SR04
HC-SR04 Ultrasonic Sensor: Overview
The HC-SR04 is a popular and affordable ultrasonic distance sensor module commonly used in robotics, automation, and other applications where distance measurement is required. It uses ultrasonic sound waves to measure distances by sending out a pulse and timing how long it takes for the pulse to bounce back after hitting an object. Key Features:… Continue reading HC-SR04 Ultrasonic Sensor: Overview
Arduino: The Open-Source Hardware Platform That Changed the World
The Arduino project began in 2005 as a tool for students at the Interaction Design Institute Ivrea (IDII) in Ivrea, Italy. The goal of the project was to create a low-cost and easy-to-use programmable platform for interactive art design projects. The project was started by Massimo Banzi, David Cuartielles, David Mellis, Gianluca Martino, and Tom… Continue reading Arduino: The Open-Source Hardware Platform That Changed the World
SCARA-Selective Compliance Assembly Robot Arm
The SCARA robot (Selective Compliance Assembly Robot Arm) was invented in 1978 by Professor Hiroshi Makino of Yamanashi University in Japan. The acronym SCARA stands for “Selective Compliance Assembly Robot Arm”. The SCARA robot was designed to be a more efficient and flexible alternative to traditional industrial robots. The SCARA robot’s design allows it to… Continue reading SCARA-Selective Compliance Assembly Robot Arm
ENIAC-The first programmable, electronic, general-purpose digital computer.
ENIAC, or Electronic Numerical Integrator and Computer, was the first electronic general-purpose computer. It was built by John Mauchly and J. Presper Eckert at the University of Pennsylvania between 1943 and 1945 and was funded by the United States Army. ENIAC was a massive machine, weighing 30 tons and occupying 1,800 square feet. It contained… Continue reading ENIAC-The first programmable, electronic, general-purpose digital computer.
