Hi, I am looking at making a board to support an individual with learning disabilities to understand the time of day passing by changing the colour of lights from green to red on each individual LED every five minutes.

I want to run two or three LED strips on the board containing 144 LED's in each one meter strip.

Please could you tell me if the Arduino Mega would be powerful enough to drive this amount of LED's?

Also what LED strips would you recommend using, I need to keep the cost down to ensure I can get authorisation to go ahead with this project.

Kind regards Jason

Quick n Dirty best describes this video lol. You got the basics down, but the actual info is fairly wrong.

The Mega can do 3.3v or 5v, with a processor speed of 8MHz (for the 3.3v version only), 16MHz, or 20 MHz, while the Uno comes in 3.3v with 8MHz, or 5v with 16MHz.

The USBs are NOT regular... They are USB 2.0 Type B, AND they both use an additional Micro Controller to handle it. The AT chips used for the Mega and the Uno do not have the ability to communicate over USB, and must rely on the secondary Micro Controller to handle that. This is why the Uno and Mega can't be seen as anything other than an Uno or Mega... You can't change its operating mode easily without risking bricking the boards completely.

Also, the Images used for the "USB" and "UART" are incorrect... As stated, the USB used is a Type B, not a Type A... And the UART doesn't use a D-Sub style connector... Most UARTs don't for that matter... they're usually just pins, or pads...
