Hello everybody! I made my white color LED bulb into a bi-color LED bulb. To see how I made it, click the link bellow. http://www.instructables.com/id/White-LED-Bulb-Into-a-Bi-color-LED-Bulb/

Hi everybody. Since last month I tried make a large salt crystal. But I couldn't. However I could make small salt crystals.

                   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

   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   

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.

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
