Sean<\/a>'s pick this week is Arduino Blinking Heart Motion Sensor<\/a> by Ye Cheng<\/a>.\r\n <\/p>\r\n <\/introduction>\r\n

My pick this week is one of the many submissions on the File Exchange that mentions Valentine's Day somewhere in the description.\r\n However, unlike any of the others, this one runs standalone on an Arduino so I can set it up somewhere in my house an surprise\r\n my wife with it.\r\n <\/p>\r\n

So what does it do? The Arduino is connected to a motion sensor and a breadboard with red LEDs on it shaped like a heart.\r\n When the motion sensor trips, it blinks the LEDs.\r\n <\/p>\r\n

The controller is built in Simulink. It uses Stateflow<\/a> for the supervisory control logic and the Arduino Simulink Support Package<\/a> so that the model can be embedded on the Arduino.\r\n <\/p>\r\n

Here's a snapshot of the Stateflow logic:<\/p>\r\n

<\/p>\r\n

So if you're curious what happened when I set this up in my house, here's a video. The motion sensor is very<\/i> sensitive.\r\n <\/p>\r\n

Many thanks to Ye for providing me with the hardware.<\/p>\r\n
