I want to display the characters that move around on the LED dot matrix. What does the program do, and what other components do I need?
I learned programming. As far as I can see, which elements of the shape of the words are controlled on the dot matrix, and then in a sequential manner, in a recursive manner (increasing the number of lights in the loop), all the way to the end, and then the loop.
Because the LED dot matrix screen is used 5V, so use 220V electric power box will turn into 5V access, if only 16 point high indoor display and a card can directly use the remote control input, the input method with a mobile phone to send text messages almost, but different card is used in computer software to edit and send to control storage the chip card on the software installed in the computer.
Very simple, and now there are many finished product control cards sold, the program is paid to send, as long as the card with the screen with a cable connection can be, of course, the power box power supply,
