TCA9548A I2C Multiplexer

TCA9548A I2C MultiplexerYou just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA SCL pins!" Are you out of luck? You would be, if you didn't have this ultra cool TCA9548A 1 to 8 I2C multiplexer! Finally, a way to get up to 8 same address I2C devices hooked up to one

wideband fully programmable RF signal generator

Parallax has a a heart rate sensing tutorial with sample code on their learning site

which can record 8~20 sec by set resistor and cycle play

Note: Mesh Bee will not communicate with Xbee as the ZigBee stack versions they're using are different

65" square body

those are not included

and you can plug it onto the Base shield and work with Arduino directly without any jumper wires
