how to minimize an arduino project
i'd like to link up this heart rate sensor http://www.adafruit.com/products/1093 to the arduino uno but only problem is that arduino is kinda too big, is there a smaller alternative to the arduino uno that l could use, perhaps around the 5cm x 5cm or smaller please?

There is the Pro Trinket that might work for you. https://www.adafruit.com/products/2000

Re: how to minimize an arduino project
If I understand the pulse sensor correctly, it needs to use the USB serial connection. I don't think the Trinket Pro provides USB serial support, and you would need to use a FTDI cable.
If you wanted to use a chip that talks directly to USB without a separate cable, perhaps the ATmega32u4 breakout board would be better: https://www.adafruit.com/products/296. Note, this is a different chip than either the Uno or Trinket Pro uses, and you may need to make some changes in the code, depending on the sensor. I suspect you don't need to make changes. You would have to change the default board when programming it.
