Telephone Remote switch
This Project is used to control our household electrical devices from any where through the cell phone. The circuit consists of a DTMF tone detector and a power...
InfraRed Remote Switch
This Project REMOTE CONTROLLED SWITCH BOARD is used to switch on/off the Home Appliances by using a standard Remote control. The system is used to switch on/off...
Tiny RC Cars - Transmitter and Charger
The transmitter runs on only 3V whereas most others run on more voltage. This dirt cheap item uses non-adjustable inductors so it is not possible to tweak for h...
IR Link
When a remote control signal is received, the energy stored in C2 drives the emitter diode. At the same time, Q1 switches on briefly to allow the battery to rec...

6 channel IR remote with PIC 16F84
This project is a remote control system based on a pic and an universal remote controller for TV, named SIMPLEX.
The IR signal of a specific remote control...
Infra Red Switch remote control
This is a single channel (on / off) universal switch that may be used with any Infra Red remote control using 36-38kHz. (This is a very common remote handset fr...

IR Remote Control Tester
As I was developing my IR Extender Circuit, I needed to find a way of measuring the relative intensities of different Infra red light sources. This circuit is t...
Infra Red Remote Control Extender
I have seen these devices advertised in magazines, they sell for around £40-£50 and use radio to transmit between receiver and transmitter. This version costs...
IR Remote Control Extender Circuit (Mark 2)
This is an improved IR remote control extender circuit. It has high noise immunity, is resistant to ambient and reflected light and has an increased range from ...
PC IR Remote Control Hardware
The hardware (as I have bullt it) is constructed from two modules, one to capture the signal and provide timing functions, and the second as transmitter placed ...
remote control and Intruder detector
These ultrasonic circuits are all quite old: my notes date them at mid-70s so they don`t use ICs. Nevertheless there are several places where an op-amp would po...
Infrared circuits for remote control
Infrared remote controls are using a 32-56 kHz modulated square wave for communication. These circuits are used to transmit a 1-4 kHz digital signal (OOK modula...
