2 4 Ghz Transmitter And Receiver Circuit Diagram. To operate a rc car quadcopter drone rc plane rc boat we always need a reciever and transmitter suppose for rc quadcopter we need a 6 channel transmitter and receiver and that type of tx and rx is too costly so we gonna make one on our own with arduino and nrf24l01 module and you can also use it to operate various servo s and this rx tx can be used for any circuit which needs a tx. Below pictures showing the rf transmitter circuit with breadboard setup.
1 transmitter section this section comprises of a ht12e encoder chip rf transmitter and antenna are shown below. Working of circuit circuit connections. In this project i will use rf modules with pic 16f628a.
After you learn ho rf modules communicate with each other you can use these modules with pic microcontroller ardunio or any microcontroller.
Block diagram of rf transmitter and receiver. This distance should be less than about 50m depending on the walls in between. This circuit however suffers from three important drawbacks. 4 two 12v universal regulated power supplies one for 20w model because a power supply already built inside the tx.
