We've all been there - you've spent hours and hours trying to get that sketch working, but somehow, you're not reacting well to time critical events in your system. Maybe it's a wireless peripheral indicating when a packet is ready. Maybe it's an external Flash device signaling when data is ready to be read out. Maybe it's as simple as a button push that you need to react quickly to! But, try as you might, it seems the best way to see these sort of events is to just digitalRead() that pin over and over in your main loop() function until something interesting happens. ...or is it?

The LM35 is an ideal temperature sensor for measuring ambient temperature. It provides a linear output proportional to the temperature, with 0 V corresponding to 0 degrees C and an output voltage change of 10 mV for each degree C change. LM35s are easier to use than thermistors and thermocouples because they are so linear and require no signal conditioning.

In some Arduino applications, it is advantageous to be able to store and retrieve information locally. You can do this with a Secure Digital, or SD, card. An SD card is a non-volatile memory card used extensively in portable devices, such as mobile phones, digital cameras, GPS navigation devices, handheld consoles, and tablet computers. Another type of SD Card is the Micro SD card. Measuring only 15 mm x 11 mm x 1 mm, it is the smallest memory card available. It is about one-quarter the size of a normal-sized SD card, or about the size of a fingernail.
