Title Design of the Infrared Remote Control Motor Speed Circuit Based on EDA Development Platform
Abstract Nowdays the electronic design automation (EDA) technology and infrared remote control technology is used more and more extensively in the fields of scientific research and development. When you design electronic products, if you use the tool of EDA to do aid analysis and optimize design in circuits, you can not only save money but also shorten the time of design. And infrared remote control technology is a kind of wireless and contactless control technology. It has some significant advantages, such as strong anti-interference, reliable information transmission,low power consumption, low cost and so on. So it has been widely used.This topic is based on the EDA technology, combined with the infrared remote control to realize the DC motor speed control and the control method is pulse width modulation (PWM).
Keywords Electronic design automation (EDA) Infrared remote control Pulse width modulation (PWM) Motor
