When it comes to giving your projects wireless capabilities, A 433MHz RF Module is the most common and easiest way to get things done. A 433MHz RF module uses the ASK modulation methods to transmit ...

In this project, we’re making an ordinary two-wheeler helmet smart using an RF Transmitter & Receiver. The best part: this Arduino-based smart helmet is simple to build and does not require advanced ...

Making our projects Wireless always makes it to look cool and also extends the range in which it can be controlled. Starting from using a normal IR LED for short distance wireless control till an ...

You can learn a lot from old-school projects. Consider this wideband RF signal tracer circuit from 1988. If you're interested in RF technology and circuit design, you'll enjoy this design. You can ...

It is often required to switch electrical appliances from a distance without being a direct line of sight between the transmitter and receiver. As you may well know, an RF based wireless remote ...

This application note describes system-level characterization and modeling techniques for radio frequency (RF) and microwave subsystem components. It illustrates their use in a mixed-signal, ...

The transmitter module consists of three pins that is VCC, Data and GND. The VCC pin has a wide range input voltage from 3V to 12V. The transmitter consumes a minimum current of 9mA and can go as high ...
