This video shows my “Romantic Lighting Sensor”. It let’s me know when my place is lit romancally. It is one of Robert Faludi’s example projects in his book “Building Wireless Sensor Networks”. The video above shows the basic version where the yellow light starts to shine if the lighting is good enough. The Red flickering light indicates if the XBee’s are communicating with each other.
“The Doorbell” is one of the first exercises in Robert Faludi’s book “Building Wireless Sensor Networks”. An XBee is attached to an Arduino to make wireless communication between the two boards possible. When the button is pushed on the button-board, it sends a signal (“D”) to the other board. This board, the bell-board, receives this signal and responds with the sound of a buzzer.
