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
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

Recently on the Raspberry Pi 2 toss video, used to do FPV, but found that the 2.4G control will seriously interfere with 2.4G WIFI, in the open control when my desktop + external USB card is frequently dropped. Consider a bit, although the 5.8G frequency band is lower than the 2.4G penetration, but at this stage 5.8G is cleaner, and 5.8G and 2.4G do not have a frequency-doubling relationship, it is not easy
