Using the hybrid rf xmit receive modules make building the rf remote control a lot easy.
4 channel remote control circuit diagram.
Transmitter works with 5v to 12v dc.
5 vdc 200 ma.
Gnd this should be connected to ve terminal of a 5v battery or gnd pin of arduino.
The received signal is demodulated and fed to pin 14 of the ic.
Pin 14 is the input of the built in inverter inside the ic.
There are 7 pins in the receiver module.
5v this should be connected to ve of a 5v battery of vcc pin of.

Simple 4 channel on off remote control introduction.
Pt2262 used as encoder transmitter and pt2272 m4 decoder receiver ics are heart of the project.
The first part of the circuit is a radio receiver built around transistor q1.
Receiver circuit is connected to ac appliance via relay so that we can control the light remotely.
In this remote controlled switch circuit we are using tv remote to on off the ac light by pressing any button of remote and using the tsop1738 at receiver end.
5 channel radio remote decoder.
The 4 channel rf receiver and transmitter can be used with or without an arduino.
Pressing buttons 1 2 3 or 4 turns the corresponding output on pressing it again turns it off.
Rf 4 channels remote transmitter.
This is a very simple wireless rf transmitter circuit that consists of the holtek ht 12e encoder chip and am 418mhz transmitter module wz x01 other similar device can be used.
4 channel infrared ir remote controller is using ht12a and ht12d encoder decoder chips from holtek.
3 to 5 vdc 5 v 20 ma receiver.
Rf 4 channels remote transmitter circuit.
The receiver provides 4 channel momentary outputs.
Remote receiver decoder circuit.
We have used ic 4017 to convert it into a push on push off switch.
The transmitter can be powered with any voltage from 3 to 12v.
You can connect relays to the receiver outputs to control it wirelessly.
The remote receiver circuit is built around the ic rx 2b.
The remote control operates on the infrared principle with a range of up to 50m.
This device is good for switching on and off up to 4 independent appliances by remote control.
