Hello all,
I want to design a basic circuit which measure the usage time of another circuit. Basically, the circuit should measure the on time of the other circuit when it is powered and it should count the hours of operation (and keep the value when circuit is not powered. it should go on counting where it stopped after the circuit is powered again). As soon as the desired operation time is reached let's say it should flash a red LED to indicate the user and a button can reset the timer after the part is replaced with the new one . Could you give me some keywords for my google search or some examples? I am trying to avoid using microcontrolers or highly specific systems because the main circuit is pretty basic.
Cheers!
