i am trying to build a time delay circuit for my car. the output from the 74LS193 Qa, Qb, Qc, Qd will be connected to a AND gate. when 1111 is present at Qa, Qb, Qc, Qd, this will then send a '1' to the motor. i wanted the motor to start moving after like 1-2sec after '1' is send to the motor. wht do i nd in order 2 build the delay circuit that is connected from the output of 74LS193 to the motor?
