100% selfmade - 25 standard cyan/green LEDs with selfetced PCB and ATiny2313 (now ATMEGA8) Controller - Software made with Bascom AVR take a look at ledstyles.de
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 ;-)
I guess you use C++ language for the project? What is the name of the program call?
