To solve the problems of the static display approach, multiplexed display method is used. Here 4 seven segment displays connected using multiplexed method. Here common anode seven segment LEDs are used. Anodes are connected to +5V through transistors. Cathodes of all seven segments are connected in parallel and then to the output of 7447 IC [...]
