we have this project...we have to make a circuit with 3 input and the out put is through a 1 digit 7 segment common annnode. can some one give me a diagram?
at first glance I would say get 3 diodes and a resistor and make a diode AND or OR gate and maybe buffer it with either a BJT or if you want to get all IC a 74HC14 Schmitt inverter to clean it up as well
