i'm looking to setup a timer circuit, that is triggered on the downswing of a pendulum. the pendulum induces voltage in a coil to trigger the timer on. the pendulum, however, passes over the coil twice per swing, once on the down swing, and once on the up. i only want it to trigger on the down swing.
would using a lm555 in a delayed retrigger setup, a al **broken link removed** , be a feasable set up for this?
(after the downswing trigger, i'd have the delay set to a time less than the time it takes for the bob to reach the top of its swing, and return for most of the down swing. the delay ends sometimeframe before the instant it retriggers.
