Yea, there are different methods of wiring the solenoid to the spike.
We only see one solenoid type in FRC. They are all simple coils that get energized or not, essentially, two single solenoids in one package.

Typically, the major variations you'll see in wiring a double solenoid on FRC robots are:
  • Use two outputs on the Pneumatic Bumper w/o a spike at all (diagram 3 below). This is the easiest choice.
  • Use diodes to direct the current flow from the spike to a either side of the solenoid (2nd diagram below). Jeremy's favorite method.
  • Cross-wire the sides of the solenoid to a spike (first diagram below). This is the way I usually tell people to wire a double solenoid to a Spike.
All three methods work fine. It's just a matter of choice and circumstances.
