Internet of Things With the Raspberry Pi 2

More and more home automation projects are integrated into an Internet of Things (IoT) perspective. For example, you want to monitor what’s going on in your home remotely, no matter if you are in your living room or at the other end of the world.

Arduino, How to know the state of an output pin?

When your program set state on an OUTPUT pin, it can be sometimes useful to know the state of this OUTPUT for some reasons (sending the output state over internet, etc…) So here is the trick to know the output state of a pin: //exemple for the state of the pin 3 Serial.println(bitRead(PORTD,3)); But why?
