What is aRaspberry Pi?

● Credit card sized computer● Runs a version of the Linux Operating System● 2 or 4 USB ports (depending on the version)● On-board Ethernet● PLUS: Features programmable GPIO Pins

○ GPIO pins let the Raspberry interact easily with other things such as LEDS, temperature readers, and more!

● It is NOT an Arduino
