These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop. That outputs both the audio signal and a 40 kHz carrier signal, implemented using the ...

We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are identical to concepts used in cell phones and Wi-Fi. Initially we ...

It has an RF front end for up and down-link , ... ATA8520 is a transmitter-only version of the same IC that works from 1.9 to 3.6V. Crypto engine: No: ... ATA8520-EK2-E extension board is designed for ...

In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to six relays and monitor two analog signals.
