The answer here is picked at random. A real pendulum is moved by tiny unconscious hand movements (the ideomotor effect), so neither one is evidence that something is true. Use it to notice what you hope the answer is.

How this reading works
A pendulum held over a board often seems to move by itself. Researchers explain this as the ideomotor effect: tiny, unconscious muscle movements, named by William Carpenter in 1852 and studied with pendulums by Michel Chevreul. The swing can mirror what you already feel. Here the answer is chosen at random as a prompt for reflection.
You ask a yes/no question; the virtual pendulum swings and settles at random on yes, no or maybe. With a real pendulum, the swing comes from your own tiny hand movements.
Pendulum use belongs to radiesthesia and dowsing. Their motion is generally attributed to the ideomotor phenomenon — small unconscious muscle movements — and there is no scientific evidence for radiesthesia.
Cultural, safety and licence notes
Pendulum answers are not evidence of anything. Controlled tests of dowsing have found it no more effective than chance (see the Wikipedia article on dowsing); never use a pendulum for health, safety, pregnancy or money decisions.
