Hacker le contrôle parental de votre décodeur TV SFR Je sais, je sais… Vous allez me dire ‘pas bien’ mais prenons le cas tout simple qu’un de vos enfants s’est amusé avec votre télécommande de votre décodeur TV SFR et que par mégarde il a entré un code parental. Et bien sûr il ne se rappelle plus du code. Comment faire pour désactiver cette fonctionnalité ? Il existe une procédure pour réinitialiser le décodeur TV SFR (sortie usine) ou on peut tout simplement le faire à l’aide d’un Arduino !!!

In this post I am going to show you how to use and program IR LED and Photodiode pair with Arduino to detect obstacles in a short range. Before going to do the project let us have a brief look at the IR LED and Photodiode.

Photodiode is a light sensitive semi-conductor diode which converts the light energy into voltage or current based on the mode of operation. In general Photodiodes are operated in reverse bias condition. The clear Photodiode can detect visible and IR rays to limit the Photodiode to detect only IR rays a black cotting is applied to the glass of the Photodiode. The photodiode allows the current to pass through it if the photodiode is exposed to IR rays and it doesn't allow current to pass through it if no IR rays falls on it. The amount of current passed through the photodiode is directly proportional to amount of IR rays falls on it. IR LED and Photodiode Project: Materials required: 1) Arduino 2) IR LED 3) Piezo buzzer 4) some Wires.

Circuit diagram: How circuit works: LED Sensing. A little used technique is to use an LED as both a light emitter and a light detector. Just like a dog walking on its hind legs one marvels, not that it is done well, but that it is done at all. Theory It is a little known fact that an LED can be used not only to generate light but also to sense it. However, from a solid state physics point of view a diode is simply a PN junction, so a rectifier diode, light emitting diode and photo diode basically are all the same thing.

A semiconductor can be doped or mixed with two types of impurity that result in material that conducts electricity in two different ways. So when a P and N type material come together to form a junction some of the holes in the P type materiel move into the N type material where the combine and cancel each other out. To get electricity to flow you have to apply an external voltage that adds more electrons to the N side and more holes to the P side. Practice So let’s see how we can make use of this effect. Hardware Software. Aergia: Android controlled TV Remote(with Speech Recognition) Have you ever faced this situation while sitting on your favorite spot on the couch or recliner, comfortably watching your favorite TV program?

You're snugly tucked under the blanket, the air conditioning is pleasantly cool, the sun outside is shining it's delicate warm golden rays on the closed window, the air (from the air vents) is refreshing and gravity seems infinite...... It's almost like nature doesn't want you to get off your couch....... Then all of a sudden a horrible commercial pops up on the TV and you desire to switch the channel immediately. However, the TV remote which is located just beyond your arm's length seems to be many miles away and you do not have the energy nor the will power to reach for it. You then look with disappointment at your aging Android phone which is near you and hope that you could use it to control your TV. So let's get lazing....... SB-Projects: IR Remote Control. IR Remote Control Theory The cheapest way to remotely control a device within a visible range is via Infra-Red light. Almost all audio and video equipment can be controlled this way nowadays.

Due to this wide spread use the required components are quite cheap, thus making it ideal for us hobbyists to use IR control for our own projects. This part of my knowledge base will explain the theory of operation of IR remote control, and some of the protocols that are in use in consumer electronics. Infra-Red Light Infra-Red actually is normal light with a particular colour. We humans can't see this colour because its wave length of 950nm is below the visible spectrum. Although we humans can't see the Infra-Red light emitted from a remote control doesn't mean we can't make it visible. Unfortunately for us there are many more sources of Infra-Red light. Modulation Modulation is the answer to make our signal stand out above the noise. The Transmitter The Receiver The End? A Multi-Protocol Infrared Remote Library for the Arduino. Do you want to control your Arduino with an IR remote? Do you want to use your Arduino to control your stereo or other devices?

This IR remote library lets you both send and receive IR remote codes in multiple protocols. It supports NEC, Sony SIRC, Philips RC5, Philips RC6, and raw protocols. If you want additional protocols, they are straightforward to add. The library can even be used to record codes from your remote and re-transmit them, as a minimal universal remote. To use the library, download from github and follow the installation instructions in the readme. How to send This infrared remote library consists of two parts: IRsend transmits IR remote packets, while IRrecv receives and decodes an IR message. #include <IRremote.h> IRsend irsend; void setup() { Serial.begin(9600); } void loop() { if (Serial.read() ! This sketch sends a Sony TV power on/off code whenever a character is sent to the serial port, allowing the Arduino to turn the TV on or off. How to receive Hardware setup.
