Here is a hobby circuit of a multi channel remote control system, by which you can control 8 different appliances. The main sections of this multi channel remote control circuit are the RF receiver and transmitter. By using this circuit we can control 8 devices, each of them independently by pressing the push buttons. Here the relay load current is dependent on the relay used.

You must need a regulated power supply of 5 volt for this circuit because ICs and requires 5v for its operation. So we are using a voltage regulator IC which provides 5V output. It is again decoded by a 3 to 8 decoder IC to operate the relay.

Output of is the clock of JK flip flop IC which operates in toggling mode. Hi LunaeMaster I have no simulation of this circuit,but i tested this circuit already. Hi, Unfortunately by a typing mistake your last question was deleted, Anyway here is the question and answer.

It's all about procuring the RF modules ready made from the market by spending a few bucks and configuring them together for the intended results. Here I'll show you how to make an approximately meter range RF remote control circuit using RF modules, without the help of any microcontroller stage.

To begin the assembly you will have to procure the following readymade RF modules and the respective encoder and decoder chipsfor the present project we use the HOLTEKs modules:. The above encoder and decoder ICs do the jobs exactly as per their assigned names that is encode and decode the bit information for enabling easy interfacing with analogue circuits.

Configure the transmitter circuit by assembling the Tx Transmitter Module with the Encoder IC as given in the following circuit:. Thus the latch breaks only when a different subsequent output is rendered high through the Tx relevant push buttons. Meaning VT output can be used in case a flip flop is required to be operated.

The above can be very easily interfaced with a relay driver stage for operating any equipment such as a remote bell, lights, fans, inverters, automatic gates, locks, RC models etc. The pinouts AA7 of the Rx, Tx modules are very interesting. Here we can see them all grounded which creates an impression that these are of no use and are simply terminated to ground.

It's simple, let's say for pairing the above modules we ensured that the address pins are identically configured. Alternatively we could make the above pair unique let's say by opening A0 for both the modules. This will make the pair respond only with each other and never with any different module. Similarly if you have more number of such pairs and want to make unique pairs out of them, just assign the pairs in the explained manner. You can do this by either connecting the address pins to ground or by keeping them open.

It means by rendering different configurations to the relevant address pinouts between A0 and A7 we can create a huge number of unique combinations. The above simple RF remote control circuit was successfully tested by Mr. Sriram on a breadboard, the following images of the built prototype were sent by him for reference.

4 Channel Wireless Four Button Remote Control Transmitter Receiver Module (Mode: Non Locking)

Building a hi-end remote control device using very few components today looks pretty plausible. The proposed remote control light switch circuit idea provides you with the opportunity of building and owning this amazing device through simple instructions. Moreover the unit provides a 4-bit data to be exchanged between the transmitter and the receiver modules. This Hi-tech remote control light switch enables you to control four individual lights or any electrical appliance for that matter from any corner of your house remotely using a single tiny remote control hand set.

Imagine switching a light, a fan, washing machine, computer or similar gadgets from any corner of your room without taking a step! Controlling a particular gadget remotely through a single flick of your finger definitely feels very amusing and amazing too. It also gives you the comfort of doing an act without moving or getting up from a particular position.

The present circuit idea of a remote control light switch enables you controlling not only just a single light but four different electrical gadgets individually using a single remote control hand set. The IC TWS basically does the function of manufacturing and transmitting the carrier waves into the atmosphere. Datasheet TWS However every carrier signal needs modulation for its proper execution, i.

This function is done through its complementing part — the HTE 4-bit encoder chip. It has got four inputs, which can be triggered discretely by giving them a ground pulse individually. Each of these inputs produces coding which are distinctly different to each other and become their unique signature definitions.

The encoded pulse from the relevant input is transferred to the IC TWS which carries forward the data and modulates it with the generated carrier waves and finally transmits it into the atmosphere. The above operations take care of the transmitter unit.They are widely applied in the majority home electronics enthusiasts, industrial remote control electronic product design and development can be very good as a single-chip signal input source, especially for students and colleges electronic circuit design, the graduate design of the remote control circuit portion.

Caution: Take care while handling the receiver module, that onboard copper coil inductor should be untouched. When a key is pressed, the IC is connected to power supply battery and it starts transmitting packets at Mhz frequency consisting of its ID and Data byte which indicates which key was pressed. This information is used in remote control applications. Each transmitter has a pre-programmed unique ID set during manufacturing and cannot be changed.

The receiver board usually stores the transmitter ID in its memory before so the receiver only responds to known transmitter IDs for secure applications. Output also has known jog output data pin output level is instantaneous and the transmitter and whether transmission corresponds, can be used to control similar to jogging, a remote control signal data pin is high, the signal disappears when the remote data foot immediately restored to the low level, for applications such as electric doors, electric door locks, and SCM docking requires only a high level of circuit and other circuits and so on.

Here Data output pin enables the trigger to flip operating logic, and data can be kept as long as the successful reception of the corresponding level state change until the next time the remote data changes. Self-locking independent of each other four, four simultaneous remote control, such as lighting control and the like. VT output status indication. D3 data output. D2 data output. D1 data output.

The whole project contains two parts, which is an FM transmitter and a RF receiver. For good results use a good quality FM transmitter with the circuit.

We have used our best FM transmitter circuit with 9V battery as a transmitter with this receiver and it was working well. The receiver circuit only detects the RF signals so there is no need of microphone with the transmitter.

433MHz RF remote control system based on PIC microcontroller

The receiver circuit can be operated with 3V to 12V DC. The current consumption of the circuit is very low and in standby mode the circuit drains only uA due to which it is ideal to be operated with batteries. As you know the circuit is RF based so it requires some tuning for the first time. After building both parts of the circuit i. FM transmitter and the receiver circuit attach 80cm antennas telescopic or wire at both units and first check if the FM transmitter is working properly by tuning it on any good FM receiver.

After that tune the transmitter on the RF receiver by adjusting the pF trimmer in the receiver circuit until the proper transmitter signal is received. Now slowly make distance between the transmitter and the receiver and adjust the trimmer at both sides. The sensitivity of the receiver circuit can be adjusted with the K variable resistor.

Slowly adjust it for the maximum sensitivity by placing the transmitter many meters far from the receiver. It is suggested to use a slightly big variable resistor. With big variable resistor the circuit can be easily tuned to its maximum sensitivity.

After tuning the circuit with a big variable resistor you can use a fixed resistor. The Coil L1 in the receiver circuit is a hand made air cored coil having 6 turns of 24 enameled wire wound closely on a 5mm form. Electronics Beginner Guide Tutorials.The TX-2B forms the main part of the circuit. These push button switches are interfaced to the built-in latch circuitry of the TX-2B.

C2 is the filter capacitor while C1 is a noise by-pass capacitor. The encoded control signal will be available at pin 8 of the IC. The encoded signal available at pin 8 is without carrier frequency.

This signal is fed to the next stage of the circuit which is a radio transmitter. Crystal X1 sets the oscillator frequency of the transmitter section. R2 is the biasing resistor for Q1 while R3 limits the collector current of Q1. The encoded signal is coupled to the collector of Q1 through C3 for modulation.

Transistor Q2 and associated components provide further amplification to the modulated signal. The first part of the circuit is a radio receiver built around transistor Q1. 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. C12 is the filter capacitor while R11 is the current limiter for the radio receiver section. Diode D2 protects the circuit from accidental polarity reversals. C15 is another filter capacitor and C14 is a noise by-pass capacitor.

The method for interfacing a relay to the output of RX-2B is shown below. This makes the transistor 2N to conduct and the relay is activated. The same technique can be applied to other output pins of the RX-2B.

The relay used here is a ohm type and at 9V supply voltage the load current will be 45mA which is fine for 2N whose maximum possible collector current is mA. When using relays of other ratings this point has to be remembered and do not use a relay that consumes a current more than the maximum possible collector current of the driver transistor.Making our projects Wireless always makes it to look cool and also extends the range in which it can be controlled.

In this project we will learn how we can build wireless projects using a MHz RF module. These modules are cheap for its functions and are easily available. Let me give brief intro to these RF modules before getting into the project.

A RF transceiver module will always work in a pair that is it needs a Transmitter and Receiver to send and Send data. A transmitter can only send information and a Receiver and can only receive it, so data can always be sent from one end to another and not the other way around.

The Transmitter module consists of three pins namely Vcc, Din and ground as shown above. The Vcc pin has a wide range input voltage from 3V to 12V. The transmitter consumes a minimum current of 9mA and can go as high as 40mA during transmission. The center pin is the data pin to with the signal to be transmitted is sent. The speed at which it can transmit data is around 10Kbps. The Vcc pin should be powered with a regulated 5V supply.

The operating current of this module is less than 5. The pins Dout and Linear out is shorted together to receive the Mhz signal from air. This signal is then demodulated to get the data and is sent out through the data pin.

The RF modules can also function without the need of Encoder and Decoder modules.

Simple 16-channel ON-OFF remote control

Simply power on both the modules with the corresponding voltage mentioned above. Now, make the Din pin on transmitter high and you will find the Dout pin on receiver also goes high. But, there is a big drawback in this method. You can have only one button on the sender side and one output on the receiver side.

This will not help in building better projects, so we employ the encoder and decoder modules. As said they have 4-data bit and 8-addresss bit, these 8 address bits has to be set same on both the encoder and decoder to make them work as a pair. The complete circuit Diagram including the Transmitter and Receiver part for this project is shown in the images below.

Since the transmitter does not need a regulated 5V we have directly powered it with a 9V battery.
