Simple Beeper Circuit
How to build a simple beeper circuit is described in this article. An unbalanced multivibrator is a type of electrical circuit that produces sound when a button is pressed. A little speaker produces the sound. Learning about music and electronics through this project is fun. What is a Beeper Circuit: The Beeper circuit is a […]
Simple Adjustable Oscillator Circuit using Two Transistors
This article teaches how to use just two transistors to create a little sound generator circuit! Turning a knob will change the sounds pitch from high, like a beep, to low like a growl. Either four AA batteries or a tiny wall adaptor can power the circuit. To explore how electronics may generate sound perform […]
Simple LM386 Audio Amplifier Circuit
A common chip known as the LM386 is used in this post to show how to construct a circuit for a small amplifier. It is low cost, easy to build and can boost the volume on once speakers or music player. Though it is less strong enough for massive shows but this amplifier is ideal […]
Simple Piezo Buzzer Circuit
This project makes sound in a whole new way. It is quite easy to build and only uses a few parts: A transistor like a tiny switch A special coil like a mini electromagnet A tiny speaker component piezo transducer that turns electricity into vibrations The result is a high pitched sound kind of like […]
Simple Li-Fi Transmitter Receiver Circuit
Think of the internet as light instead of radio waves. Exactly that is what Li-Fi technology achieves. Building a simple Li-Fi system to transmit and receive data using light is explained in this article. A bright LED and a standard transistor are used by the transmitter to convey the signal. The receiver picks up the […]
