IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller

Introduction  This little project will demonstrate how you can use your old NEC IR protocol based TV,DVD or VCR remote control to control you home appliances like fan bulb or virtually anything. Consumer IR protocols There are a number of consumer Infrared protocols out there and they have been used for every single purpose possible i guess, like PDA laptops and other consumer appliances. RC-5 & RC-6 by ...

Servomotor-based mobile robot control

Project description:  Mobile robots are used in many industrial, commercial, research, and hobby applications. This project is about the control of a mobile robot using servomotors. The robot used in this project is the base of a popular mobile robot known as Boe Bot, developed by Parallax (www.parallax.com and www.stampinclass.com). The basic robot is controlled from a Basic Stamp controller (Trademark of ...

Sensored BLDC Motor Control

In a DC motor, the stator is a permanent magnet and the rotor has the windings, which are excited with a current. The current in the rotor is reversed to create a rotating or moving electric field by means of a split commutator and brushes. On the other hand, in a BLDC motor, the windings are on the stator and the rotor is a permanent magnet, hence the term inside-out DC motor is coined. To make the rotor t ...

8 Channel IR Remote Control

This IR remote control that you can use to control other devices or circuits up to 8 devices. The control codes are sent in RC5 format modulated to about 38 kHz carrier frequency.The IR transmitter powered by the CR2016 which is a 3V button Cells Battery CR2016.To extend the life of the battery this is done by putting the CPU into SLEEP mode for most of the time and wake-up only when a key is pressed. PIC16 ...

Industrial Small Engine Control

An industrial plant is designed with different control systems in which it varies according to the equipment to be controlled. This design is a general-purpose engine control system, which handles fueled or electrically supplied small engines of industrial plant. It features a 1.0A power relay control, 2.0A relay for fuel pump control, and a lamp driver. The system is also capable of start-up/shut-down cont ...

First Servomotor Control Program

In our first program , we will simply sweep the servomotor from CCW to CW and then sweep back. The program will be kept simple as to demonstrate the priniciples of controlling a servo with a the PIC Basic language. The schematic can be seen in figure 2 (below). The variable pw controls the pulsewidth, and is started at 100 (extreme left, -45 degrees). The program sends the pulse out to the servo, and then i ...

Infra red remote control tester for Philips RC5 protocol

Philips invented the RC5 protocol for controlling electronic equipment such as CD players, VCR’s and audio amplifiers way back in the 1980’s. The RC5 standard has been adopted and used with great success ever since, which means it is probably the most common IR remote control format in your home today. We have recently been playing around with a PIC microcontroller based RC5 decoder programmed in C, with th ...
