The circuit of the Arduino-based FM receiver, shown in Fig. 2, is built around Arduino UNO board (board1), TEA5767 radio receiver module (FM1), LM386 low-power amplifier (IC1), 16×2 LCD (LCD1) and ...

This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

The friend’s radio didn’t come with a frequency display, and buying the add-on would cost more than the radio did. So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS ...

Arduino in Control. AR1, an Arduino Nano board (see Figure 4), is used to control this digital FM receiver. It drives a standard 8 x 2 character alphanumeric LCD (LCD1). It reads and reacts to the ...

The circuit exemplifies the use of ZN414 IC to produce a handy AM radio receiver. ZN414 IC– a composition of transistor tuned radio frequency (TRF) circuit packaged in a 3-pin TO-92 plastic package ...

This project is an FM radio receiver based on Arduino programming language, using the LGT8F328P microcontroller, the RDA5807M receiver module, a 0.96" OLED display, and a rotary encoder. In this ...

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive… ...

Arduino RF Transmitter Circuit Diagram. Our wireless doorbell project will require a transmitter and receiver circuit each with its own Arduino board. The Circuit diagram for Doorbell Transmitter is ...

Here at RF Transmitter side, we have used Arduino Nano. Wiring the receiver module is also very simple, and once again you only need to make three connections. Connect the modules VCC and ground pins ...

A. Circuit Analysis Figure 1 shows the schematic diagram of the device. As it is clear, the circuit consists of 3 main parts: Arduino-Nano (Controller), FM receiver module, and the audio amplifier.
