I'm very new to Arduino UNO (only one basics course). I have a very specific project that requires a "one shot" circuit to take the input from a reed switch (activated by spinning magnets under a disk) to turn a LED light off and on and be adjustable. See attached diagram
Here"s a schematic suggested by a uTube video on the subject .
Does anyone have a suggestion for a sketch for this?![](http://strobe circuit.jpg)
Thanks for any advice.
