OR gate

Outputs 1 when at least one of its input is 0.

The OR gate is a binary device. If any input is 1, output 1. Otherwise output 0. Since this is a binary device, the input value is rounded so any value ≥0.5 is equal to 1.

Essentially, it acts as a reverse Y-splitter and can combine two inputs into one.

Truth table

Lua implementation

local in0 = this:read(0)
local in1 = this:read(1)
if in0 >= 0.5 or in1 >= 0.5 then
    this:write(0, 1)
else
    this:write(0, 0)
end
