How To Make RF Transmitter And Receiver


Hi friends in this video we are going to make radio receiver and transmeter circuit let’s get started if you haven’t subscribe my channel then subscribe and don’t forget to press the bell icon for updates circuit diagram is in the description comment if you have any queries and suggestions first connect encoder ic to breadboard this circuit will be operated on 5V supply connect pin 18 to positive supply connect pin 9 to negative supply connect 1M resistor to pin 15 and 16 connect transmitter module connect Vcc pin to positive supply connect Gnd pin to negative supply connect its data pin to to pin 17 of encoder ic encoder and transmitter is connected connect 4 push buttons to breadboard connect 10k resistor to each button and Gnd then connect first button to pin 10 then connect second button to pin 11 then connect third button to pin 12 then connect forth button to pin 10 connect other pins of buttons to positive supply connect 0.1uf capacitor to supply pins connect pin 14 to gnd to enable the circuit transmitter circuit is ready let’s make receiver circuit connect decoder ic to breadboard connect pin 18 to positive supply connect pin 9 to negative supply connect 47k resistor to pin 15 and 16 connect 4 leds to breadboard connect negative pin of each led to gnd connect 100 Ohm resistor to first led and pin 13 connect 100 Ohm resistor to second led and pin 12 connect 100 Ohm resistor to third led and pin 11 connect 100 Ohm resistor to forth led and pin 10 connect receiver module to breadboard connect its negative pin to gnd connect its positive pin to positive supply connect its data pin to to pin 14 of decoder ic both circuits are completed i am using diy breadboard supply to receiver circuit the supply has 0.1uf cap so i am not using it set the power supply to 5v connect supplies to circuits
