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 then […]

Inside Measurements Using Vernier Caliper
In this video, I demonstrate how to use manual vernier calipers to measure the inner space or dimensions of an object.. Significant figures is also discussed.
My Weekend Project: Sound Location Finder
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. If […]
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
