5 channel radio remote decoder
The remote receiver circuit is built around the IC RX-2B. 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. R2 sets the frequency of the IC’s internal oscillator. O/P 1 to O/5 are the output pins that are activated corresponding to the push buttons S1 to S5. Zener diode D1 and resistor R12 forms an elementary Zener regulator for supplying the RX-2B with 3V from the 9V main supply. 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.
Notes. This circuit can be assembled on a vero board or a PCB. Use 9V DC for powering the transmitter / receiver circuits. Battery is the better option for powering the transmitter / receiver circuit. If you are using a DC power supply circuit, it must be well regulated and free from any sort of noise. Both ICs must be mounted on holders. Interfacing relay to the RX-2B output.
The method for interfacing a relay to the output of RX-2B is shown below. When push button switch S1 of the transmitter circuit is pressed, pin O/P1 (pin 7 of the RX-2B) goes high. This makes the transistor 2N2222 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 200 ohm type and at 9V supply voltage the load current will be 45mA which is fine for 2N2222 whose maximum possible collector current is 900mA. 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.

Matheus Gabriel says: May 26, 2014 at 5:55 pm Hi I built the circuit of TX in a printed circuit board, and now, I need to build the RX My doubt is how I crank the engine that my car with the circuit of RX? We have two engines to crank. How I make it? Reply
Seetharaman says: May 27, 2014 at 8:17 am If you want to crank two together use one output with a relay’s two NO (normally open contacts) contacts. Reply
Victor says: May 28, 2014 at 2:14 am Hi Seetharaman, just so u know i had another question on that 2km transmitter posted since last friday. Reply
Matheus Gabriel says: June 14, 2014 at 7:45 am OK, but i wouldn’t rather use relay. I saw on the datasheet of Silan, this circuit have been actived by transistor. Can I use these? Please, help me! Reply

Khadija says: April 14, 2014 at 2:35 am 1) Sir you said it’s 5 channel remote control but how can i connect the motors? 2) and how can i control the motors? 3) and sir the value of R9 is missing. Thank you. Reply
Seetharaman says: April 16, 2014 at 12:24 am
It is just with high low output only you have to use proper interfaces to drive motor on/off forward/ reverse etc. analog control of speed is not possible (slow fast etc). R9 is 100 K ohms 1/4 watt see earlier detailed comments. Reply
San says: February 26, 2014 at 4:13 pm where is C9 for the receiver Reply taher says: February 16, 2014 at 2:42 am the R9 value is now mentioned there could u pls give the reason or tell something to find it out with some sort of method or pls give the value of that resistor Reply
