Dynamic Microphone Preamplifier Circuit using IC uA739
Dynamic microphones are popular in audio recording and sound systems because they are tough, long-lasting and can handle loud sounds really well. However, they usually produce a weak output signal, which means you often need a preamplifier to make the signal strong enough for further use or amplification. The circuit shown here is a preamplifier […]
Active Crossover Circuit using IC LM324
An active crossover circuit is a key part of audio systems that divides an incoming audio signal into different frequency ranges so they can be amplified and played separately. This helps make sure that each frequency range goes to the right speaker like a woofer for low sounds and a tweeter for high sounds, which […]
Simple Arduino FM Receiver Circuit
This project shows how to use an Arduino Uno microcontroller to create a basic FM radio receiver. The RDA5807M, a highly integrated FM radio module, is the receivers brains. This module may convert FM radio transmissions into audio signals after receiving them. The audio signal is then sent through a 3.5mm audio connector after being […]
Simple FM Radio Jammer Circuit
The purpose of an FM radio jammer circuit is to produce signals that obstruct FM radio broadcast reception. Communication on FM frequencies may be hampered by this interference by competing or noisy broadcasts. A transistor for oscillation, capacitors for tuning, a coil for producing the radio frequency signal, and resistors for circuit stability are usually […]
