I'm having some difficuly understanding how the display "SURE ELECTRONIC P4 32X8 3208 RED LED DOT MATRIX UNIT BOARD SPI LIKE" Arduino UNO works.
- I would like to add some buttons and potentiometers to the system. For example: by pressing the 1st button the name display with the memorised name could light up per minimum 30 seconds and so on for the entries on the other buttons.
- I would like to know how to add two potentiometers: one to adjust the speed of sliding and one to adjust the time.
Thank you in advance.
Looking forward to your kind reply.
