The relay shield is controlled through pin Digital 4 on your Arduino via a transistor labeled "Q1"
The GAU-RH-1X-1W Remote LED Head from Larson Electronics is a compact luminary designed for use with GAU-EMG-EXT-3L-DF (emergency bugeye system)
The EPL-SL-PT-6X150LED-RT-EPP-MOD2 is universal voltage capable and can be operated with 100-277V AC
This compact device operates on 12-200V DC
and is rated IP66 for ingress protection against dust and direct exposure to high pressure water spray
Servo Gear - Futaba (20T; Metal) OOS The relay shield is controlledThese servo gears are made specifically to fit a Futaba 3F servo spline, allowing you to mate other gears to your servo. They have 20 teeth with a gear pitch of 32P, an outer diameter of 0. 688, and utilize the 3F Futaba servo spline.
