Lessons You Should Know
Sparki comes with an infrared remote control, similar to the kind used to control TVs. It is used to send infrared codes to Sparki, which it can receive with its infrared remote receiver.
This command returns the last code that was sent to Sparki. It returns this number in the form of an integer. If there has not been a code sent since the last time Sparki ran this command, it will send back a -1.
SparkiDuino already has code examples for you to use:

How It Works
Each button on the remote sends a certain code to Sparki, which it can receive with its infrared remote receiver. The codes each button on the remote sends is listed below:
Using the Part
With the basic Sparki code in place, you can measure an infrared sensor by using this command:|

sparki.readIR(); |
