R/C Circuit:  (electronic circuit added 4/05)

R/C Digital Camera Controller:  (electronic circuit added 4/05)

R/C Switch:  This circuit is a so-called "Radio controlled Electronic Switch". It can be used to switch on/off anything electrical, whatever it is. Here are a couple of examples: navigation lights, landing gear, sound systems, Glowplug driver, bomb release, parachute, search lights, gyros, and so on. This circuits connects to a RC car controller servo output. (added 4/05)

Radio Remote Control using DTMF #2:  Here is a circuit of a remote control unit which makes use of the radio frequency signals to control various electrical appliances. This remote control unit has 4 channels which can be easily extended to 12. This circuit differs from similar circuits in view of its simplicity and a totally different concept of generating the control signals..... (added 09/05)

Radio Remote Control using DTMF:  (electronic circuit added 10/05)

Rc5 IR Remote Control Transmitter:  In this Application Note the widely used RC5 coding scheme from Philips will be described and a fully working remote control solution will be presented. This application will use the ATtiny28 AVR microcontroller for this purpose  (app note added 3/05)

RD68HC908IRC : MC68HC908QT2 Based Simple Infrared Remote Control Reference Design:  Motorola has developed a simple, single dedicated device, infrared remote control designed to control a DVD player. This reference design demonstrates how to time and create modulated infrared signals used to control six basic functions of the DVD player.  (app note added 6/06)

RD68HC908LHID : LIN-bus HID Lamp Levelling Stepper Motor Control using the Motorola 908E625:  This reference design describes a car High Intensity Discharge (HID) lamp leveling system with a LIN-bus interface. An essential part of the system is a stepper motor controller operating as a LIN-bus slave (LIN Stepper Controller). All functionality is provided by a general purpose LIN-bus IC MM908E625 and LIN Stepper software (HC08 software). The LIN Master consists of a master control board, based on an MC9S12DP256 CPU, and a personal computer with a graphical user interface (GUI), running in a master software environment.  (app note added 6/06)

Remote Charging Circuit uses Three Wire Sensing:  05/25/95 EDN Design Ideas / (added 4/05) Remote voltage sensing usually uses a four wire sensing System, this System works with three Wires

Remote Control Encoder/Decoder with PIC16c620 and PIC12c508:  (electronic circuit added 09/04)

Remote Control for Sony a /  Volt Equipment:  PIC based remote controller for Infrared and wired Control-S bus (added 4/05)

Remote Control Tester:  (electronic circuit added 10/05)

Remote Control Turns Battery on and Off:  09/12/97 EDN-Design Ideas / (added 4/05)  

Remote Control using Telephone #2:  (electronic circuit added 10/05)

Remote Control using Telephone:  Here is a tele-remote circuit which enables switching "on" and "off" of appliances through Telephone lines. The circuit described here can be used to switch up to nine appliances (corresponding to the digits1 through 9 of DTMF the Telephone key-pad). The Telephone can be used to switch on or switch off the appliances also while being used for normal conversation. (added 4/02)

Remote Control using VHF Modules:  (electronic circuit added 10/05)

Remote Control:  This is a simple wireless remote control unit, which was originally designed for a model hovercraft which I was developing with the help of my friend Uday Arya. The project has been discontinued for technical reasons, but this remote control unit survives. The method used seems to be quite popular among many remote control units. (added 10/06)

Remote humidity sensor needs no Battery:  04/04/02 EDN Design Ideas  /  (added 1/05)  Using ac-line power sources and batteries for remote humidity sensors is undesirable because these sources can be troublesome if you mount them in inaccessible points, such as smokestacks, cold-storage chambers, or darkrooms, where maintenance is difficult and inconvenient. Figure 1 shows a simple way to remove the power source from the humidity-sensor circuit. ...
