Hey I need some help from someone smarter than I am please!
I’m trying to figure out how to make 2 plastic arms to move away from center and back at the same time.
All 3 pieces are plastic about 6” tall. Center piece remains stationary.
Left arm is mounted at the bottom in the front of the center piece.
Right arm is mounted at the bottom in the back of the center piece.
Both arms should move back & forth at the same slow rate kind of like flower petals opening and closing.
Continuous operation plugged into a standard home outlet is preferred.
Please see attached diagram and advise.
