Intro: Digital UV-meter, With OLED Display. Arduino Project for Beginners

Video demonstration (English subtitles).

Hello, instructable. Today I will tell you how to make a simple digital VU meter (sound level meter) using Arduino and OLED displays and 2 resistors by yourself (DIY). The device is quite simple, for beginners it will be a rewarding experience.

STEP 1: Components for This Arduino Project:

  1. Arduino Nano V3.0;
  2. 0.96 inch IIC I2C 128X64 OLED Display;
  3. One 10K, resistor(R1 no scheme);
  4. One 10K-100K potentiometer(R2no scheme);

  5. Wires.

STEP 2: Device Circuitry

As you see the scheme is extremely simple, every novice will make.

  • Resistor R1(10K) it is necessary!
  • Potentiometer R2 may have a nominal value of 10K up to 100K.It is used to adjust the sound level.

STEP 3: Source Code

ArduinoVuOledMeter.ino - all this - the mathematical magic.

display.c - BMP-file to convert to an array of points. It must be located near the ArduinoVuOledMeter.ino.

STEP 4: Enjoy

Created by Techn0man1ac.

P.S. If you want a stereo version - make two identical devices.

Not good enough, change the download .ino file.

I used another library for the display, in my opinion the code works faster with it

In my version of Arduino IDE 1.6.9 everything works fine

Is the floating image due to the camera or is it real ?
