No idea on how to google for a circuit that can do this: I will have a piezo sensor/disk that when hit softly will turn led1 and then led2 with a delay of say 5ms. On the other hand if I hit the piezo sensor harder it will turn led1 and led2 with a delay of 1ms. In summary , led1 turn inmediatly in both cases but led2 will turn on with a delay depending on how hard the piezo sensor is hit. Both led turn off when led2 is lid for 1ms (or less). Please suggest a starting point. Thanks.
