SPI OLED with Ardiuno

Image
                   Hi. Today I show you how to use OLED Display with Arduino UNO . first of all, you need an Arduino board and an OLED Display. OLED DISPLAY   There are many types of OLED displays by color & type of connection. In this   experiment, I   used a 128*64 blue color SPI OLED display. Arduino Board   In this    experiment,  I used Lakduino UNO    which is   an 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-GF

Simple music generator with Um 66

Image
   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 Quantity Ic UM66 1 2Sc828 1 100ohm 1 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. please add a comment   

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             copperselfate             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.

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

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. Download Please add a comment

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 resistor thin 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.....
