Headers
CWe have provided 6 headers that can be used for expanding the capabilities of the sprout board to add additional sensors, input devices or control external devices. On the left side we have 2 analog terminals and on the right we have 4 Digital terminals. These terminals all have a set of three sockets that all use the same configuration of 5V+ on the left, I/O in the center and Ground on the right. In addition the two analog ports can simply be configured as digital I/O as needed with the arduino pinmode.
