Feb 8, 2023 · In this circuit, Arduino RF transmitter has the microphone to take the audio input, and at the other part it has Arduino RF Receiver which will receive the audio from transmitter and output it using Speaker.

Jul 22, 2022 · Audio Spy Bug Receiver. The RDA5807M frequency modulation chip is as tiny as shown below. An ESP8266 12F chip is needed to drive it; as it works on I2C communication which is the same interface used with the ESP chip. This scans and matches the frequency of the receiver with the transmitted signal. RDA5807M FM Chip

In this project I will show you how I combined an Arduino Pro Mini with a couple of complementary components in order to create a voice recorder which could also be abused as a spy bug. It has a run time of around 9 hours, is small and super easy to use.

I designed an FM audio bug spy device whose range is up to 1km (or even more). The audio is both transmitted and received via frequency modulation. I am a guy who is influenced by fictional movies and series……

Have you ever wanted to broadcast your own radio station within your neighborhood? Ever get curious on where people get those "Surveillance Bugs" from spy and action movies? This small and simple FM transmitter is the toy that geeks have always wanted.

Jan 17, 2025 · Here we’ll discuss how to build small FM transmitter circuits using 10 different methods, one that consists of wire link from the transmitter to the receiver, and the other which is completely wireless and can be used to eavesdrop a particular conversation over a range of about 30 meters, over an ordinary FM radio.

This audio spy bug is highly customizable and can be easily integrated with other devices and systems. The NFR24L01 module allows transmission over specific channel, ensuring that our transmissions remain private up to a level.

Feb 8, 2023 · In this project, we are going to build an audio bug using Arduino and NRF24L01. This audio spy bug is highly customizable and can be easily integrated with other devices and systems. Check...

Apr 16, 2025 · Keep in mind that for both the transmitter and receiver the connections with the Arduino are the same. NRF24L01: Arduino Uno: GND: GND: VCC: 3.3V: CE: 9: CSN: 8: SCK: 13: MOSI: 11: ... Arduino based Audio Spy Bug using NRF24L01. Create a wireless audio surveillance system using Arduino and nRF24L01 modules.

Nov 29, 2020 · In this article I am going to tell you how you can make a spy bug audio surveillance listening device using Arduino. Using this mini device you can listen audio from anywhere using gsm network. you can record this audio on your phone so it is a gsm bug spy listening device.
