Logic gate
AND, OR, NOT, NAND, NOR or XOR of its inputs, set on its sheet.
In the game
How to get it
At the grid: a silicon on top, 2 signal cables on each side of epoxy, 2 plastic at the bottom corners: 2 gates. Choose the operation on its sheet.
What it is for
Combine conditions: a door that opens when both buttons are pressed, a pump that stops when a tank is full OR a valve is shut, an alarm.
Why it exists
Logic is how machines decide.
The same text the game shows in its progress tree and on the item's sheet (I).
How to get it
At the grid: a silicon (top middle), 2 signal cables round epoxy, 2 plastic in the bottom corners: 2 gates.
How it works
Inputs A and B, one output. Modes: AND, OR, NOT, NAND, NOR, XOR, computed on all 8 bits of the signals (NOT = 255 - A, XOR = A ^ B). The symbol is engraved on it.
Right-click a block to place it, facing you. Broken, it comes back whole.
