process_iconselamat siang teman teman howrudi.com mohon maaf selama ini jarang membuat artikel atau upload artikel coding dan desain elektro sendiri karena kesibukan menyusun tesis. hari ini aku upload coding pembuatan led matrix dengan susunan led 24×6 rangkaian akan saya upload dikemudian hari…hari ini saya upload coding saja.
