Using the TDA7052A audio amplifier to generate a five octave, linear in pitch voltage-controlled oscillator (VCO).

If you've never heard of a 'DAC' before, you might be surprised to hear that you most likely use one everyday. DAC stands for digital-to-analogue converter and any device that delivers digital sound – ...

An audio amplifier was once a fairly simple analogue device, but in recent decades a typical home entertainment amplifier will have expanded to include many digital functions. When these break ...

This is a library for Arduino devices. It provides an abstraction layer for general purpose input/output scenarios to read pin states, detect pin changes, debounce buttons, switch relays, blink leds ...

The analog value from the sensor is converted to distance using either a polynomial fit function up to fifth order or a power fit function. By default, this library is set to use polynomial ...
