You just need to draw the circuit.
The circuit needs to drive 60 LEDs which are arranged like in the attached picture:
Four times 3 x 5 matrixes to display numbers.
The LEDs will have a flow voltage of 2.8-3.5V.
The whole matrix display with the 60 LEDs will be connected to a micro controller through max. eight wires total.
Design the driving circuit. It should be cheap and all components need to be available at both: [login to view URL] and mouser.com.
Add a little bill of material with the order numbers.
If possible, draw the circuit with Autodesk Eagle.
The best circuit wins.
