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.

I love DIY and I especially love LED's, so that's why I decided to make my own 3x3x3 LED Cube! You will need the following items to make this LED Cube: • 27 single colored LED's. • Arduino Nano or one of his bigger brothers. • 3 NPN Transistors. I used the BC547. • 3 pin headers with 3 pins. • 1 pin header with 4 pins. • A piece of perfboard. • A few small cables. Ad

Ultrasonic Distance Sensor in Arduino With Tinkercad

  Ultrasonic Distance Sensor in Arduino With Tinkercad Let's measure distances with an ultrasonic rangefinder (distance sensor) and Arduino's digital input. We'll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to   read a pushbutton   and   PIR motion sensor   with Arduino's digital input, and we'll build on those skills in this lesson. Ultrasonic rangefinders use sound waves to bounce off objects in front of them, much like bats using echolocation to sense their environment. The proximity sensor sends out a signal and measures how long it takes to return. The Arduino program receives this information and calculates the distance between the sensor and object. Find this circuit on Tinkercad Explore the sample circuit embedded here by starting the simulation and clicking on the proximity sensor. This will activate a highlighted area in front of the sensor with a circle "
