SPI OLED with Ardiuno

Hi. Today I show you how to use OLED Display with Arduino UNO. first of all, you need an Arduino board and anOLED Display.

There are many types of OLED displays by color & type of connection. In thisexperiment, Iused a 128*64 blue color SPI OLED display.
Arduino Board
In this experiment, I used Lakduino UNO which isan Arduino compatible board. But you can use any Arduino board for this like pro, Nano, Leonardo etc.
Connecting Display to Arduino
My OLED Display has 7pins.

 OLED                  Arduino
    GND   ------->   GND
    VCC    ------->  3.3v
    CLK    ------->   D12
    MOSI  ------->   D11
    RES     ------->   D10
    DC       ------->  D 9
    CS       ------->  D 8

* However, my display worked without connecting GND and VCC.

Compile and upload code to Arduino
now we're going to upload the code for Arduino.
to do this you need Arduino IDE, Adafruit-GFX-Library and Adafruit_SH1106 library.
Libraries and source file can download fr…

Simple music generator with Um 66

Hi, this is my school vacation. So I show you a simple circuit that makes music. Do you know what is um 66 ic. That is a small ic. It includes music tones. So, in this circuit we use this ic.
List of electronic components
Componet QuantityIc UM6612Sc8281100ohm1

Circuit Diagram
First time make it on a breadboard and check it. If it is working properly, you can make it on your own PCB or a dartboard. Pin configurations of UM66 and 2SC828 are given below.

how to find is this food has protein

hello there, in this post I show you how to find protein. what are you need:-
            a solution from a food
             sodium hydroxide
            a test tube 1. add sodium hydroxide for food which you choose for this experiment 2. now add a little from coppersulfate.3. if your food has protein, the solution maybe purple.

Let's make Oxygen H2O2 + KMnO4

In this video i show you a way to make oxygen at home.

The Halloween (Game)

Hello there, In this Halloween season, I made a mini game. It name is "The Halloween". I give you it free.
I think you enjoy from playing this game.

How to play
It's very easy. you have to collect all the jack o lanterns. But,  you have to be careful with ghost.

Wireless Electricity

Welcome. Today I show you how to transmit electricity without wires. (wireless)  This is a simple circuit that work with 3v.

The Transmitter

You need :-

any kind of npn transistor that work with 3v (2SC828, D400, BC547)1K resistorthin copper magnet wire (I found that from old transformer)                
Coil wind 30 turns from any magnet wire that you found.Now tap it by 15 t and it connect to positive of battery

The Receiver You need :-     LED (any colour)magnet wire

You Can Use It for.....
