Rf Transmitter Circuit Diagram. Robotics without Microcontroller Circuit Diagram. The video above explains the basic theory that relates to data transmission namely how electromagnetic waves are generated by antennas and how they encode 1s and 0s.
The circuit is divided into transmitter and receiver sections. Circuit Diagram of RF Transmitter and Receiver. VCC GND Data and Antenna.
The frequency can also be changed by changing the value of C1.
The receiver section consists of RF Receiver HT12D Decoder IC and four LEDs. It will be a short tutorial about rf. This is probably become the simplest radio frequency RF transmitter that you will find anywhere. The transmitter part consists of Arduino UNO and the 434 MHz Transmitter module.
