The widespread radio frequency broadcasting technique known as FM (Frequency Modulation) transmission is used to transmit audio signals. The creation of an Arduino FM transmitter has grown in popularity among enthusiasts due to the growing interest in do-it-yourself electronics projects. Using an Arduino Uno, KT0803K FM transmitter module, 7809 voltage regulator, and a basic antenna, […]

Simple Long Range IR Transmitter Circuit
Compared to a basic circuit, a simple long range infrared transmitter circuit may transmit infrared light over a longer distance by using easily accessible components. The fundamental concept is to manipulate the infrared light emitting diode IR LED to produce pulses of light. Most infrared receivers are built to detect a particular frequency that is […]
Simple FM Microphone Transmitter Circuit
An FM microphone transmitter circuit is a gadget that transforms sound captured by a microphone into a radio signal that an FM radio within a specific range may receive. Using a single NPN BC547 transistor, a simple FM microphone transmitter circuit was created. A significant distance may be covered by the FM signal transmitted by […]
Simple Phone Transmitter Circuit
A phone transmitter circuit is a bug transmitter circuit designed to convert sound waves from your phone conversation into electrical signal that can be transmitted over long distances. These circuits are typically used in landline telephones. Circuit Working: Parts List: Category Description Quantity Resistors 10k, 47k, 330Ω (1/4 watt each) 1 each Capacitors Ceramic 47pF […]
Long Range FM Transmitter Circuit (2km)
This long range FM transmitter circuit is like a tiny radio station in a box. It can take your music or voice from a microphone and send it out over the airwaves much farther than a regular bluetooth speaker. This makes it great for things like community radio stations, wireless speakers for big backyards or […]
Simple Spy Phone Bug Transmitter Circuit
A ‘spy phone bug transmitter circuit’ is a secret listening device. It can pick up and send phone conversations without the people on the phone knowing. These devices are called ‘bugs’ or ‘transmitters.’ It is wrong to use these devices because they eavesdrop on peoples private conversations. It can also be against the law depending […]
