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 ...

If we want to implement the project without the library, then we need to change the receiver part of the circuit. VirtualWire.h is a special library for Arduino created by Mike McCauley. It is a ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

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 ...

Signals from the Arduino can be sent to the transmitter as a result of this interface. The arduino signal is mixed with the manual input and the resulting signal is received by the radio-controlled ...

433MHz RF Transmitter and Receiver Module: Let me give brief intro to these RF modules before getting into the project. The term RF stands for “ Radio Frequency ”. A RF transceiver module will always ...

First-person-view (FPV) flying, by adding a camera, video transmitter, and video goggles to the meat on the ground, is one of the best ways to experience remote-controlled flight. For just a few hu… ...

Today, we’re assembling and wiring a 3D printed Arduino-based pistol-grip radio transmitter that operates entirely based on Arduino-compatible electronics and is intended for anyone looking to control ...
