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:

3 More Images
  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

Picture of 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.
