Want to add a human element into your Arduino projects? You need a Pulse Sensor! This video, narrated by a voice that sounds suspiciously like Christoper Walken, gives you tips, tricks, and advice for getting the Pulse Sensor up and running. Either Joel and Yury (creators of the Pulse Sensor) are in pretty tight with Mr. Walken or they know someone who’s good at impersonations. I’m guessing the latter.

You can pick up a Pulse Sensor in the Maker Shed.
