Access Raspberry Pi on Smartphone using VNC | RealVNC

VNC

RealVNC: Remotely accessing Raspberry Pi Graphical Interface using smart phone. For this I have used VNC. In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.VNC is platform-independent – there are clients and servers for many GUI-based operating systems and for Java. Multiple clients may connect to a VNC server…

Connecting ESP8266 with Raspberry PI

ESP8266

                                    Connecting the ESP8266 Wi-Fi module to Raspberry Pi.The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer, Espressif Systems. The chip first came to the attention of western makers in August 2014 with the ESP-01 module, made by a third-party manufacturer, AI-Thinker. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. However, at the time there was almost no English-language documentation on the chip and the commands it accepted.The very…

Raspbian Jessie | PIXEL | SEP-2016 Release | Explore

Raspbian is a free operating system based on Debian optimized for the Raspberry Pi hardware. An operating system is the set of basic programs and utilities that make your Raspberry Pi run. However, Raspbian provides more than a pure OS: it comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation on your Raspberry Pi. The initial build of over 35,000 Raspbian packages, optimized for best performance on the Raspberry Pi, was completed in June of 2012. However, Raspbian is still under active development with…

Getting Started with Smallest Arduino | Digispark AtTiny85

The Digispark is an Attiny85 based microcontroller development board similar to the Arduino line, only cheaper, smaller, and a bit less powerful. With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE the Digispark is a great way to jump into electronics, or perfect for when an Arduino is too big or too much. Specs: Support for the Arduino IDE 1.0+ (OSX/Win/Linux) Power via USB or External Source – 5v or 7-35v (12v or less recommended, automatic selection) On-board 500ma 5V…

Raspberry Pi 3 as BLE Beacon

               Bluetooth beacons are hardware transmitters – a class of Bluetooth low energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets and other devices to perform actions when in close proximity to a beacon. The first commercial implementation of bluetooth beacons was by an Australian company called DKTOB (trading as Daelibs), who leveraged Bluetooth for indoor proximity sensing in its Seeknfind location attendance solution. Daelibs designed and manufactured a bluetooth beacon for use in shopping centres based…

DHT11 | Interface using JAVA | Raspberry Pi

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old. Source : Adafruit…
