Description: This project shows an Arduino project that displays the approximate frequency as well as the musical note played on an electronic keyboard or piano app. For this project, the analog output from the sound module detector is sent to the A0 analog input of the Arduino Uno. The analog signal is sampled and quantized […]

My Weekend Project: Audio Frequency Detector Using An Arduino
Description: This Arduino project displays the approximate frequency of the loudest sound detected by a sound detection module. For this project, the analog output from the sound module detector sends the analog audio signal detected to A0 of the Arduino Uno. The analog signal is sampled and quantized (digitized). A Fast Fourier Transform (FFT) is […]
My Weekend Project: Sound Location Finder
Description: In this video, I create a sound location finder using two microphone sensors in conjunction with an Arduino Uno. When the sound location finder circuit detects a sound from one microphone sensor and not the other, the Arduino request a stepper motor to turn the sound detection board in the direction of the sound. […]
My Weekend Project: Sound Direction Tester
In this video, I test two DAOKI microphone sensors with my Arduino Uno to create a sound direction tester. Arduino Sound Direction Tester
My Weekend Project: Restoring An Old Atari 2600
As a kid, I would look inside electronic items trying to understand how they work. As an engineer, I have a good idea of how they work and can restore them to working condition if necessary. In this video, I restore an old Atari 2600 I owned as a kid. Follow me as I do […]
