These days, 433-MHz RF transmitter/receiver modules are very popular with electronics ... As you can see, the setup is on the Arduino ground with a 433-MHz receiver module and the USB interface. The ...

Even the transmitter generates ... With the new setup, the Arduino has to read this, also, and make small adjustments to the frequency. The RF circuits in the radio took some modifications ...

What do you get when you combine a direct digital synthesis (DDS) chip, a power detector, and an Arduino ... feeds a two-transistor amplifier. The circuit will output about 0dBm into 50 ohms.

Both of the freestanding modules (NS73MFM transmitter, Arduino UNO) can be mounted to a breadboard and interconnected. Refer to the hardware setup and proceed. The simple code generates digital tones ...
