My arduino is struggling with keeping up on data transfering to a display

(deleted)

scooter4848: Hi,

I have an issue with my Arduino project. I have built a RPM display for a PC but im now at a stage of where when i use this display the read out keeps cutting out. Ive been told it might be that the Arduino board isn't transferring the data to the display quick enough. I'm not powering the board from a USB hub, its a direct connection to the PC. I am using a 4 mt USB cable. The display starts bright but then its gets duller until it cuts out then goes on/off.

heres the link to what i have made

any suggestions would be greatly appreciated

You do not state which Arduino board you are using. Are you using an Arduino Nano? Which version of Arduino IDE? Which operating system are you using? Linux, Raspberry Pi , MacOSX, or Windows you are using a 4 meter usb cable? that is may be part of the issue. I tend toward power issue. The power requirement may be more than the PC USB port is able to provide on a constant basis.

Try powering it from a powered USB hub. The powered USB hub should provide enough power.

You may just need to provide the nano with it's own power rather than the PC USB power, as you may be overdriving the limit of the USB.
