Understanding IR Remote Protocols to build your own IR Signal Decoder using TSOP and PIC Microcontroller IR remote is one of the simplest, easiest, and cheapest ways to transfer data wirelessly. The range of this device is not that much but that's exactly why it is perfect for simple Home Automation projects, TV Remotes, and others. Because of such a project, I had to interface an IR remote with a PIC microcontroller. My initial objective was to find a library for IR… |

IR Decoder for Multi-Speed AC Motor Control Single-phase alternating current motors are typically found in household items such as fans, and their speed can be easily controlled when using several discrete windings for set speeds. In this article, we build a digital controller that allows users to control functions such as motor speed and operating time. This article also includes an infrared receiver circuit that… |

Long Range IR Transmitter Circuit One of the most commonly used sensors in Electronics is IR sensor (Infrared Sensor). IR sensor helps in detecting the heat and the motion of an object. In the infrared spectrum, all the objects emit some form of thermal radiations. These radiations are invisible to a human eye and can only be sensed or detected by an IR sensor. An IR sensor consists of IR Transmitter which… |

Cell Phone Controlled AC using Arduino and Bluetooth In today’s modern world, where ever we go we have lots of electronic devices around us. But, out of all, there is only one device that we personally have in our pockets all the time. Yes, it is our mobile phones. Now Mobile phones have become more than a device used for communication, they are our cameras, they are our maps, they are our shopping karts and what not? … |

Universal IR Remote Control using Arduino and Android App I started this project in order to get rid of various remotes at my home and build something single which could incorporate features of all of them. I got this idea when I saw one of my friend’s mobile phone with built in IR blaster, at that time I decided not to buy a similar phone rather make my own device which should be compatible with my existing handset. So here we are… |

IR Based Security Alarm IR based security alarm circuit can detect any movement and trigger the alarm. This circuit is very useful in homes, banks, shops, restricted areas where an alert alarm is needed on any movement. This circuit is based on IR sensor where an IR beam is continuously falling on a photodiode, and whenever this Infrared beam breaks, by any kind of movement, alarm is triggered… |

IR Sensor Module Circuit Sensors are very important part of electronics, especially in Robotics and Automations. Sensors in electronic devices make our life easy by automatically sense and control the devices, without human interaction. There are many kinds of sensors like Fire sensor, humidity sensor, motion sensor, temperature sensor, IR sensor etc. In this article, we will explain about IR sensor… |

Fire Alarm System using AVR Microcontroller In this project, we are going to make a Fire Alert System using ATMEGA8 microcontroller and fire sensor. Fire sensor can be of any type, however we are using IR (Infrared) based Fire Sensor. Although IR based Fire Sensors have some disadvantages mostly of inaccuracy, it is the cheapest and easiest way to detect fire. … |

Remote Controlled Light Switch IR LED emits infrared light, and used in TV remotes. This Infrared is received by the receiver TSOP17XX (TSOP 1738used in TV). TSOP17XX receives the modulated Infrared waves and changes its output. TSOP is available in many frequency ranges like TSOP1730, TSOP1738, TSOP1740 etc. Last two digits represent the frequency (in Khz) of modulated IR rays, on which TSOP responds.… |

Automatic Room Light Controller with Bidirectional Visitor Counter Often we see visitor counters at stadium, mall, offices, class rooms etc. How they count the people and turn ON or OFF the light when nobody is inside? Today we are here with automatic room light controller project with bidirectional visitor counter by using Arduino Uno. It is very interesting project for hobbyists and students for fun as well as learning… |

Reverse Car Parking Sensor Circuit This car parking assistant can protect your car from any damage while reverse parking. It indicates the distance of car from any object and raise an alarm when it reaches close to the wall or the object and needs to be stopped. This car parking sensor circuit is quite easy and uses few commonly available components which are listed below. … |
