connecting sensors to raspberry pi

Use Raspberry Pi to send push notifications to smartphones This project explains how to send push notifications from Raspberry Pi to iOS and Android devices. You only need to use a free push app. The main idea here is to use an electromagnetic sensor door to trigger information push events. When the electromagnetic doo

The Internet of Things (IoT) and Bitcoin (Bitcoin) are all fun new things today, so what's the point of putting them together? In short, it is the use of Bitcoin networks for secure, autonomous trading of transactions involving computing resources, storage resources, bandwidth, data, and even public displays that can help other devices display content. The middle will involve sensors, IoT short-range communication protocols, cryptographic currencies a

Objective:Raspberry Pi has a variety of networked ways, either via a wired network or via a wireless network. Through the wired network connection is relatively simple, in the DHCP-enabled router, directly plug in the network cable can be networked, this article introduces the way of the Raspberry Pi wireless networking. Without the network, if there is no screen

hardware involved : Raspberry Pi and related kits, LED traffic lightsknowledge : Circuit Test Board, CanakitWhen you're ready, we can start. Use Raspberry Pi for LED prototype control.The first thing to understand is that access to all of the wires, resistors, and the lights that come with the kit need to be handled wi

ShieldsA Few other cool maker things worth pointing out is Windows Remote Arduino and Virtual Arduino Shields. Remote Arduino lets your Arduino from your Windows machine using the Firmata protocol. Then your can reach out to an Arduino device and give it commands from a Windows Universal app. The virtual Arduino Shields lets you with a Windows Phone as a well, just that, Virtual Shields. Shields for the Arduino can add up and when do you ' re prototyping-not want-to-shell out for a Gyro or GPS.

device I'm picking up is a sensor, not a character device, so I need to convert it. Similarly, the annotated Inwaiting () and Flushinput () functions are for character input, and I have not tested them on my machine, because sensor will keep on reporting data, simply read it.Another important aspect of hardware connectivity: The tx of the Raspberry Pi to be connected from the Rx of the device, the Rx of th

Arduino mega2560 can transmit data, but there is garbled, possibly because the mega2560 serial port has the relation.Since the module is good, I think of another test method, a module using a USB port to the PC, and the other directly to my Raspberry Pi on the UART interface.
