Hi, i have been studying the datasheet for the 4060 counter and oscillator used in the fridge door alarm project found in this website.I have tried to read the datasheet and i have seen that the delay time is obtained by the equation (2.2Rc*Cc).On substituting the values of C1 and R3, i don't get the value of 20 seconds.Could you please assist me?The datasheet is found in www.datasheetsarchive.com Also i would like to use the fridge door alarm to activate a motor that will actually close the fridge door alarm.Could you please lead me to a place where one can learn about motors.
