Using electrical components, a simple two-way intercom circuit enables communication between two places. Imagine a primitive office or home communication system. In this circuit the below mentioned components play the main role: Microphone: Transforms your speech into an electrical signal. Audio amplifier: Increases the poor microphone signals strength to the point where it can power […]

IC LM386 Based Voiceover Project Circuit
An LM386 based voiceover project circuit is a basic audio circuit that plays the microphone input signal through a speaker after being amplified by the LM386 integrated circuit. This kind of circuit may be used to create a simple public address system, audio mixing with priority for microphone input, or even a voiceover system for […]
Simple 40 Watt Audio Amplifier Circuit
A 40 Watt audio amplifier circuit is a type of electrical circuit used to boost audio signals from low power sources to a loudspeaker driving level. This lets you listen to your audio or music at a far louder volume. The IC TDA2040 integrated circuit is the center of this simple 40 watt audio amplifier, […]
Simple 5W Audio Power Amplifier Circuit
Strong amplifier chips like the LM384 are frequently found in basic electronics. The volume increase (gain) is regulated at 34 decibels (dB) inside the chip to keep costs down. Because microphones may readily attach to its ground, this chip is unique. The chip automatically lowers its power output when it becomes too hot. In addition, […]
Simple Machine Gun Sound Generator Circuit using IC 555
This project lets you build a circuit that mimics the staccato bursts of a machine gun. A trusty 555 IC chip generates a rapid fire of electrical pulses, controlling the timing of the sound. These pulses are then translated into sound by the circuit, creating that iconic ‘rat-a-tat-tat’ sound effect. Want to amplify up the […]
Simple Light Dependent Screamer Circuit
An entertaining small electronic project that produces sound according to the quantity of light it senses, is the light dependent screamer circuit. A light dependent resistor LDR or resistor that adjusts its resistance in response to light intensity is used in this circuit. All in all, the circuit functions as a little ‘screamer’ that increases […]
