A simple single transistor amplifier dramatically improves audio output of projects.
Build a DIY Level Sensor - tank monitor for volume, temperature, and humidity. Prototype for under $30.
Use gesture sensing to turn hand movements into keyboard inputs.
Using ultrasong PWM frequencies, the Arduino can now produce square tone() waves with 256 volume levels with nothing but a speaker!
Do you want to visualize the music volume on a led bar. We will make it easy as breathing specially when using the amazing 1Sheeld.
Using this preamplifier you can increase overall gain, tune frequency accordingly, enable dolby and drive one more channel for subwoofer.
To control Bass, treble and volume of sound signal before giving it to power amplifier, we have to modify the overall frequency response.
In this tutorial we will learn how to make a Volume Indicator using a Neopixel Ws2812 LED Ring and arduino. Watch the Video!
This project demonstrates a simple, easy-to-build Volume Control System, made using the Bolt Wifi Module and a Buzzer.
In this tutorial we will make a simple Volume Indicator using GC9A01 SPI Display, rotary encoder, Arduino and Visuino program.
