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 double OR Bit is a logic gate with two inputs and one output. In order for the double OR gate to output an ON signal, the first input, the second input, or both inputs need to be ON. When both inputs are OFF (inactive), the output is OFF.

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 OR Bit is good option for projects where you want to detect two inputs but don’t care which input is activated.

Anytime the OR receives a signal lower than 2.5 volts at either of its inputs, the OR sends an OFF signal of 0 volts to its output. If the OR receives a signal greater than 2.5 volts at either input, the OR sends an ON signal of 5 volts to its output.

Logic Bits like the OR 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.
