hi people, new to this site, looks great. im in need of a little help with a circuit im constructing. ive searched everywhere on the internet and cant find what im looking for. ive made a automatic motor control circuit and i want to use a light dependant resistor to trigger a 555 timer. ive tried everything i can think of. i can get it to trigger the 555 timer but stay on, i know the trigger pulse has gotta be shorter than the output. i cant find a way to do this using a ldr. any ideas??? cheers
