Push Button Display

First ever attempt at a circuit... Push button display used for place holding items in storage for specific chassis ID's. For example, the stall might house an item for chassis 135 so the operator would input 135 on the display by push button increments on each display to the number desired. Once the item is removed or if the operator wants to start over, the clear button is pressed resetting the display to zero. Circuit designed with AC to DC transformer that utilizes a full wave bridge rectifier, dual capacitors, and 1 resistor to smooth out voltage levels. Red LED to indicate off status and Green LED to indicate on status of switched circuit. Component Values: AC - 120V @ 60kHz Transformer - 10:1 Capacitors - 1 microfarad Power side resistor - 1kOhm LED resistors - 152Ohm LED's - 2V
