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 informat

tube. The pin is also attached to any of the Raspberry Pi's gpio ports. OE is the output enable PIN, which is also common in other chips. The function is to control whether the data in the latch is ultimately output to the Q0-Q7 output pin. Low-power output, high-power normally not output (neither high-level, nor low-level but high-impedance state, no power). In order to facilitate direct connection to GND, this example keeps the output data low.
