Sonic pi is an open-source programming environment designed to explore and teach programming concepts by creating sound production music processes. The Code executed by sonic pi is based on Ruby, which is a beautiful and concise programming language. This means that you can write a lot of code without having to worry too much about syntax and braces-though important for complex programs. 1. Getting Started

First, install the Raspberry Pi and Arduino development environment 1, Arduino development environment in the previous article has been explained that the need for friends can see "Arduino Control two motor Movement" this blog post. 2. Building a Raspberry Pi serial communi

Second, make full use of each piece of hardware to provide "soft" services, in terms of soft services, you can use Raspberry

Setting up Windows Ten for IoT on your Raspberry PiThis week on the BUILD conference in San Francisco Microsoft released the first preview of the Windows IoT (Internet of Thi NGS) for Raspberry Pi 2 (AS-well-lovely devices like the Intel Galileo and Minnowboard Max).First, as I mentioned in February the Raspberry

For many IoT applications, using a Raspberry Pi to build an intelligent gateway is no longer appropriate, but the market of those "XX smart", "XX center" direct seconds kill it!Hardware needs to be extended: SD card, WiFi, Bluetooth, USB hub,tft display.What software is needed: scripting engine, remote login service, Web server, messaging server, processing server, forwarding server, Smart Display software,

people a different sense of motivation and sense of accomplishment than virtual machines. Of course, in terms of playability, Raspberry Pi can also do a lot of interesting things. Daoteng aircraft, remote control toy car, controlled home appliances, control access, make super computer and so on. The main thing is to b
