This project aims to develop an affordable and efficient sound level meter using an Arduino microcontroller. The primary objective is to measure sound pressure levels in decibels (dB) and display the ...

The small LCD display provides a visual representation ... Visit the official Instructables project page to learn more about the Arduino sound meter and its construction. Full details and code ...

[hamblin.joe] wanted to do a simple project for kids along these lines, so whipped up a neat design using analog meters to display the time. The build relies on that old stalwart, the Arduino Uno ...

Hey there! 👋 I'm thrilled to share my latest Arduino project featuring an alphanumeric LCD display (LCD1602). This project allowed me to dive into the world of hardware and microcontrollers, creating ...

Just in case. Bar graph display a bit too modern-looking for you? Well then you should check out [mircemk]’s OLED version that displays dual analog meters.

and returns the sound wave travel time in microseconds return pulseIn(echoPin, HIGH); } void setup() { lcd.begin(16, 2); } void loop() { ultrasonic = 0.01723 * readUltrasonicDistance(A0, A1); ...
