The double AND Bit is a logic gate with 2 inputs. It sends an ON signal from its output only when input 1 AND input 2 are both receiving an ON signal.

Description:

The double AND Bit is a logic gate with 2 inputs and one output. In order for the AND gate to output an ON signal, both inputs need to be ON at the same time. When this happens, you are able to activate any output module like an LED, a DC motor, or a buzzer. Building circuits with logic Bits is essentially the equivalent of physical prograqmming. Logic Bits create rules for your circuit to follow, giving you more ability to create interesting and complex interactions. The double AND Bit is a good option for projects in which you want two actions to trigger another.

Real World Applications:

  • The Shift Key on a keyboard
  • Door with two locks

The double AND Bit receives two inputs and provides one output. If both of the input signals are high, then the double AND Bit will output a high signal from its output bitsnap. Otherwise it will output a low signal. Logic Bits like the double AND Bit only work with two states of inputs, ON and OFF. When an input is either ON or OFF, like a button, a toggle switch, or a sound trigger, we call it a digital input. Inputs that have variable voltage like pressure sensors, dimmers, and light sensors, are analog inputs. Because logic gates only deal with ON/OFF, high/low, or true/false, analog signals pass as digital. With analog inputs, an “ON” signal occurs at about 2.5 volts when passing through a logic gate. Also in logic circuits, you may want to hold the state of a momentary input (like a button). In order to hold this state, you can use a latch. You can also use a timeout to hold the state for a certain period of time.
