  • I guess you use C++ language for the project? What is the name of the program call?

  • no, I use Bascom Basic for AVRs

  • im new in making circuits... may i ask? in this 25 leds did you use 25 resistor too? or how many resistor do i have to use in order to do this circuit like yours..? please help

  • Well, it's a multiplexed matrix... So you have 5 lines of LEDs and 5 columns - LEDs in the Lines are all connected to each other and are activated as a column... So you need 5 resistors.

    BUT you should read up on multiplexing-matrix-displays to be sure to know what happens here ;-)
