Building the Gates
In this section, you will build both the AND Gate sub-assembly and the OR Gate sub-
assembly.There are some similarities between the two kinds of gates, so we will start by
building the common sub-assemblies used in both types of gates.
The Pistons
In the following steps, you will build a pair of joined pneumatic pistons that are the heart
of the mechanical function of the pneumatic gates.You will need to build seven of these
Piston sub-assemblies.
