littleBits o21 Number Plus

The number Bit displays information that it receives from the Bits before it. It's a great way to measure the input from sensors or count things, like the score in a game.

The number Bit displays information about the signal it’s receiving.

In "count" mode, the Bit can count up or down each time it receives an input signal over 2.5 volts. It can be reset by receiving a signal through the reset bitSnap at the top of the Bit.

In "read" mode, the Bit displays information about the signal it’s receiving in either volts ranging from 0.0–5.0 or values ranging from 0–99.

The signal leaving the Bit will always match the number being displayed, even in "count" mode. For example, if you count up to 38, the signal leaving the Bit will be 38% of full power.
