LED Project Research
To create a LED matrix I have found these instructions;
In short the above project requires;
- 64 LEDs
- 8 Resistors for the LEDs
- 1 Shift register for the columns
- 1 Driver array for the rows
- 8 Resistors for switching the driver array 1 microcontroller
- 1 clock source for microcontroller
- 1 prototyping board
- 1 power supply
- Hook-up wire
The skills needed would include soldering, connecting power supplies, component knowledge and circuit diagram knowledge.

I would also need to consider a way to allow the LED's to react to sound or a form of programable input. In the next examples a USB is used a a connection to program the device.

There are also some drivers available to achieve various results.
