Help with my University Project !!

Hi guys. I am currently working on a simple project for my university. The project is to display time, date, day, temperature and humidity in a large led board. I have made the display using three 16x32 p10 led boards connected in series. I have used arduino uno as the controller to process and send data received from RTC 3231 module (time and date) and dht 11 sensor module (temperature and humidity). To power up the led boards, I have used a 5V 10A power supply unit. Everything is working fine till now....

The problem is that I was asked to extend the project and make 3 more of the same to make the display 4-sided. I want to display the exact same data on all the 4 sides of the display. I can buy 9 more led boards and power supply for the same and make the display, but can I use the same arduino to get parallel data lines for all the 4-sides ?? Will the arduino be able to produce sufficient current to send correct data to 4 parallel data buses ?? Please Help....I have attached some pictures showing the backside of a p10 module, the connections I have used for connecting arduino to the display (which has a 16 pin input) and the project which I have made.

 

Thank you guys for the reply. I will surely check the total current drawn by the input port. Can you give me a more detailed explanation on how to use buffers??

 

Thanks a lot !!

 

It worked ! All I did was just connect the data lines in parallel using a breadboard and fed them into the 4 sets of led boards. Apparently, the Arduino was able to provide sufficient current to all the data lines with just a 5V 1A rated power supply. The only problem was that there was some flickering in some of the boards which was frustrating to look at. Later, I found that the problem was either with the AC adapter or the power supply port present in the Arduino and fortunately the flickering stopped when I used a mobile charger with a USB port to power up the Arduino. Apparently, the USB power supply was more regulated and stable than the power provided by the AC adapter to the DC barrel plug.

I have posted a few pics with all used led boards. My next step towards completion is to design a PCB which does what the temporarily used breadboard does, which I believe is not a big task. Thank you for your responses guys.
