LittleBits

The OR Bit is a logic gate with 2 inputs. If input 1 OR input 2 is receiving an ON signal, then it sends an ON signal from its output.

The NAND Bit is a logic gate with 2 inputs. Think of it as "not and." The NAND Bit will always send an ON signal unless both input 1 and input 2 are receiving an ON signal. It’s the exact opposite of the AND Bit.

The NOR Bit is a logic gate with 2 inputs. It sends an ON signal only when neither input is receiving an ON signal. In other words, it’s the exact opposite of the OR Bit. The NOR Bit is good for inventions in which you want the output to be ON, unless 1 or both of its inputs are triggered.

The USB I/O module allows you send and receive digital audio and control voltages to and from a computer. When using in conjunction with a DAW, you can record your Synth Kit directly into a computer without the need of an external audio interface. You can also send audio from a computer into the littleBits system to manipulate it, for example with the filter and delay modules.

The XOR Bit is a logic gate with 2 inputs. Think of it as "exclusive or," meaning that it sends an ON signal when it’s receiving an ON signal exclusively from 1 input or the other, but not both.
