This is a model circuit that can control the speed and the direction of a dc motor without the h-bridge ( it's an alternative to h-bridge ).
I'm trying to resurrect my aunt's home cinema DVD player.
I'm building working model of differential pressure airflow measure device with analog sensor, instrumentation amplifier and Arduino.
The automated bird repeller system seeks to fend off birds from crop fields to minimise damage and maximise crop output!
Simple Audio Amplifier based on LM386.
Here is the story behind homemade amplifier.
The TDA7294 is a monolithic integrated circuit in Multiwatt-15 package, intended for use as an audio class AB amplifier.
Want some serious sounds coming from your Arduino MEGA?

For the MCU BoosterPack Design Challenge
This project was made to monitor the level of any liquid that have water.
Presented here is the Guitar Amplifier. The best part of this project is that it is recycled and portable.
This is an amplifier with stereo input containing a bass boosting board for proper working of a 5 " subwoofer and two speakers.
An Electret Microphone Preamplifier that is a condenser mic along with a single transistor amplifier.
Tone control is a type of equalization used to make specific pitches or "frequencies" in an audio signal softer or louder.
We have a new project using the tone control circuit.
A class D audio amplifier based around a TPA3255 board with features that include preamps as well as balanced and unbalanced inputs.
I love the movie War Games, so I decided to build a 4 button sound board with an ESP32 that plays some clips from the movie!
This is the 200 Watts Mono Audio Amplifier Board. The board can play 200 watts speakers easily.
