This project brings back the old time Analog VU Meter, with the added functionality of a neat looking clock! When you turn off your music the meters automatically swing into to clock mode. Behind it all is the popular and easy to use Arduino. This is my submission for the Make-to-Learn Youth Contest: What did […]

The idea of using triangulation for distance measurements is well known since Pythagorean time, when his brilliant formula become available for mathematicians. What is new in this design, is lasers power control via “blooming” effect of CMOS camera. Here this “negative” effect was put to work instead of ADC. No need high price “no-blooming” camera!

O’K, after having some fun with stereo version of the VU meter I described in my previous blog-post, now it’s time to do a serious stuff. Studio grade VU meter !!! 24 steps, equally spaced every 3 dB, covering Extra wide Dynamic Range from -63 up to +6 dB. Single (mono) channel this time, no messing around,
Audio VU meter with Extra wide Dynamic Range 69 dB using Arduino Continue Reading
We had a project that required connection to a digital micrometer with a data output jack. The idea was to connect a microcontroller to the micrometer, to read the measurements and make decisions based on the readings. The micrometers that we used are made by Mitutoyo, and have a funky 52 character data stream in

GoFly is a project based on PNA (car navigation devices with Windows CE), LK8000 tactical fligh computer software and variometer (altimeter) external input based on Arduino board and pressure sensor. Why? -You can build this for about 150$, -Your ordinary PNA (Personal Navigation Assistant) changes to really nice, high end flying computer, with lot of
DIY wattmeter with an Arduino Measuring power and energy using regular multimeters can be challenging or even unfeasible at times. In order to conduct such a precise and reliable measurement, a specific wattmeter is necessary. Due to their high cost, an alternative option is introduced in the form of a homemade wattmeter using an Arduino

Being electronics engineers, we consistently rely on meters and instruments to gauge and study the functionality of a circuit. From basic multimeters to advanced power quality analyzers or DSOs, each device serves specific purposes. Many of these gauges are easily accessible and can be bought depending on the measurements needed and their precision. However, there

Displayed is an audio meter based on Arduino that utilizes a liquid crystal display (LCD). A VU meter, also known as a standard volume indicator (SVI), is a tool that shows the signal level in audio equipment. This project involves displaying the intensity of left and right audio signals as bars on a 16×2 LCD

Today, we will be measuring weight by connecting a Load Cell and HX711 Weight Sensor with Arduino. Weight machines can be found in various stores, and they show the weight when an item is placed on the weighing platform. Thus, we are constructing a weighing device with Arduino and load cells capable of measuring up

I have a late 80’s VW and the gauge cluster has 5 dummy LED locations underneath the other warning lights. Well I was tired of the m not doing anything, so I decided to do something about it. I came up with the idea to put a lateral gravitational force mater (G Meter) in there
