What can you do with it   Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  The big advantage of Raspberry Pi is that it doesn't have a fixed pattern. You can use it to play video or browsing the web, also can "play with" it, learn how to use this motherboard to do something, Raspberry PI is a flexible platform that can be played as a toy, a tool or experiment platform. . An ordinary computer Raspberry PI is a computer that can also be used to install free software on the web.You can use it to deal with documents or tables when you can't connect to the network. . Learning to programming Raspberry PI is designed as a teaching tool to encourage young people to carry out various computer experiments, It installs the interpreter and compiler of various programming languages. For beginners, you can use MIT and Scratch Graphical programming language. If you want to start co...

5. see the version   Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  There are so many ways to see the version: 1.by smartphone First, download two software: JuiceSSH              this is terminal AndroidVNC           this is VNC used to display the version Ensure the smartphone and Raspberry Pi has connect to the same network, you can open the USB wifi share of smartphone, then connect Raspberry Pi and smartphone with an USB cable, try to get IP of Raspberry Pi. Open JuiceSSH, set a new connect, give it a name and input Raspberry Pi’s IP, connect it, you can see that it’s easy to write command via smartphone for it has serve for many shortcut key. Set up a software by the following command: sudo app-get install tightvncserver This command ...

4.Set static IP   Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  You may say: no, though I can use Wi-Fi and don’t need network cable, I still have to use Advanced IP Scanner to search IP of my Raspberry Pi, it’s so inconvenient. I will teach you how to set static IP First: input the following command: sudo nano /etc/dhcpcd.conf Secondly: input these command to the bottom line:              interface eth0 static ip_address=       (the static IP you want) static routers=          (your routers) static domain_name_servers=     (domain) Tip : this is the way to set eth’s static IP The following is about how to set wireless static IP: Input the command: interface wlan0 static ip_addres...

1. Install IMG to your Raspberry Pi        Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on)  1.prepare for something The IMG of Raspberry Pi is named Raspbian. Download the Raspbian from the following website: https://mega.nz/#!LxcEiZ7A!PSLA5zq7Pa8DAab9gRHZkv4OwMpEGQhPAIUvhl25OXM This IMG has already added driver of Raspberry Pi’s screen. You can also download Raspbian from official website. Then, get a TF card, make sure that the storage is larger than 8G, format it, burn the Raspbian to your TF card, you can down win32 disk imager from the following website: https://sourceforge.net/projects/win32diskimager/ 2.Burn the Raspbian to TF card burn the Raspbian to a TF card by this software   You may find that the whole room of your TF card has been reduced largely, don’t worry, your TF card’s room haven’t been reduced, it’s norma...

4. Arduino Learning notebook -- Make the first circuit: Blink single LED  (VOL.1)               Juvtmall  ( a company supply  PCB Prototyping ,  PCBA service  and sell kinds of  components, modules  and so on) (  Catduino  has the same function of Arduino) In the previous  experiment , we learned how to make an  LED  to blink, and the following experiment would control six  LEDs. [ code ]  //set IO pin as controlling the LED i nt Led1 = 1; i nt Led2 = 2; int Led3 = 3; i nt Led4 = 4; int Led5 = 5; int Led6 = 6;  // Led display  style 1  sub program void style_1(void) {   unsigned char j;   for(j=1;j<=6;j++)   {     digitalWrite(j,   HIGH);     dela...

3.  Arduino Learning notebook -- Make the first circuit: Blink single LED               Juvtmall  ( a company supply PCB Prototyping , PCBA service  and sell kinds of components, modules  and so on) Before making any circuit, be sure to understand the parameters of the original in the circuit, its working voltage, working current and so on. LED ’s working voltage is generally 1.5-2.0 V, the working current is generally 10-20m A , and the reverse breakdown voltage is 5V. The control board logic circuit power supply is 5V. According to the above parameters assumption LED choose 1.7 working voltage, working current choose 15 m A , current-limiting   resistance  =( total voltage - LED voltage)/current, so the current-limiting   resistance  = (5-1.7) / 0.015 = 220 Ω. First, you need to download the compiled software from the arduino's official website, the address is http:...
