Hi Folks, I've just joined looking for help on an electronic timer circuit for indication of when my garage door is being opened and closed. I am a complete novice on electronics, retired now aged 81, been working for 47 years as an aircraft engine man from Meteors to Concorde. Always loved electronics and have built a few kits like a treasure tracer, electronic ignition timer (years back). My problems is I have fitted a M/S to the garage door run from a 12V supply to a light in my hallway together with a noise maker(old battery operated toy from my sons bike years ago) - trouble is they operate all the time. I purchased a Vellman MK111 adjustable interval timer to see if this would do the job. First is this going to be robust enough for the garage door operations, next not sure how I would wire the units up such that the noise operate for a short whereas the light needs to be on all the time the door is open. I would also like the noise to operate on closing but for a shorter time. Am I asking to much or is there a simpler way?
