This is a true 'minimalist' remote, having but three functions: Volume Up, Volume Down and Mute Volume is controlled by a motorized (motorized for US readers) pot rather than any of the 'digital' pots that now abound, and this was done for a number of very good reasons.

The encoder/decoder parts are to be connected to a transmitter/receiver module which takes care of the transmission of digital signals by radio or infra waves. The communication signal format is designed to be used for radio transmission (it has a constant 50% signal/silence ratio), but it can work with infrared devices as well.

You can construct your own long range infrared (IR) wireless remote using Motorola's MC145026 emitter and MC145027 detector chips. With your remote you can control devices up to 20 feet (7 meters) away. It operates similiarly to a TV remote. You just point the emitter at the detector, push a transmit button. The detector then interprets your data signal. You can use this circuit to remotely turn on/off devices (like a motors, relays, home appliances).

How many times you needed some remote control to handle some electric device ? many times. There are lot of remote controls like infrared, RF, SMS (like my other circuit) and more. The basic small-range remote controls are 2, Infrared and RF (Radio Frequency). One of the weaks of Infrared is that the signal can not pass the walls. So, if you want to control your garage door, the only way is to use some RF remote control. The circuit (transmitter and receiver) use few components and ordinary (I love few component circuits) . Its easy to build it because you don't have to tune-up any coil or variable capacitor. The RF modules are fix to work in 418MHz area.

RC5 Infrared Remote Control Receiver for Media Centers A few time ago I decided to create a media center box to replace my DVD player, satellite receiver, VCR and my kid's Play Station 2 , to one device. So, I made a core 2 duo processor system that actually replaced with succeed, all my electronic devices. The only thing that was missing was a remote control to switch On/Off my Media Center. After I searched on the net to buy a complete remote control system, I saw that the price was a little bit high (about 90 euros). I checked my stuff to find my old 7-in-one remote control that I had bought 2 years ago and I started to build my own remote control receiver circuit.

This project is an expansion from another project from this website. On the one side you can read the RC5, RC5X and RC6 codes from remote controls on a LCD and on the other hand you can send all thinkable RC5, RC5X and RC6 codes to a device. Besides is for this project a PCB layout drew to make it still more easier for you.

This project is a 2 channel infrared (IR) remote controlled relay driver with power saving. It works with 12-bit SIRC IR signals as used by Sony remote controls. The board uses Microchip's low cost PIC10F200 microcontroller along with a handful of easy to find components making this possibly the lowest cost remote controlled relay driver around. The controller also features a power save feature which reduces the relay holding voltage to 50% of the relays nominal operating voltage once the relay has switched on.

The UIR is a device that enables you to control your PC with ANY remote controller you have (TV, VCR, CD or Stereo). Original hardware & software was designed by Martinus & Ties Bos. You should check their site first. There it was, now it has either moved or is unavailable. In this article you can find improved and simplified hardware scheme, software & hints for building the device. The device is very simple: minimal version uses only 3 components! So if you are not planning a big serial production you will build it on experimental (universal) circuit board. This is the most correct schema:

This is an 8 Channel RF Remote Transmitter and Receiver that will allow to remotely control various electronic projects. RF Remote Control provides 2 latched and 6 momentary outputs that could be used to control your favorite devices such as amplifier, robotic devices, RC cars, computer, home appliances, lamps and many other cool gadgets.

This is an assembled 4 Channel RF Remote Transmitter and Receiver with an impressive 200m range. Is simple to connect and it will allow you to remotely control various electronic projects. RF Remote Control provides 4 momentary outputs that could be used to control your favorite devices such as amplifier's volume control, selection of audio sources, wireless light control, light dimmers, robotic devices, motors, RC cars, computer, home appliances, and many other cool gadgets. If required momentary outputs can be easily converted to toggle with 4013 digital low cost IC.

These tiny RF modules are great for building your own wireless remote control or wireless link. Remote control that allows to control different devices can be easily implemented with wide range of encoder/decoder chips (such as HOLTEK HT12E + HT12D or MC145026 + MC145027) or PIC / AVR microcontrollers. RF Module can also be used for sending data at up to 4.8KB/s.

This is an 8 Channel IR Remote Transmitter and Receiver based on SM5021 encoder and SM5032 decoder ICs. It is simple to build and will allow you to remotely control various electronic projects. IR Remote Control provides 2 latched and 6 momentary outputs that could be used to control your favorite devices such as amplifier's volume control and selection of audio sources, wireless light control, light dimmers, robotic devices, RC cars, computer, home appliances, and many other cool gadgets.

On these pages, I will introduce Remote Controller with Radio Frequency. The electric wave sending-out is controlled with the code by PIC for transmission and the code is deciphered by PIC for receiving.
