Hello all,
I have a project where I need to control a 9x9 grid of LEDs effectively wired in parallel. I will have a microcontroller controlling this array, but it only uses ±5v on its output pins.
What would be the best way to step the 5v signal down to 2v while still allowing the signal to be changed rapidly for PWM?
To clarify on the LED's connection:
Each column and row is connected to the microcontroller by 1 pin, for a total of 18 pins. Each of the microcontroller's pins may be supplying a signal to 1-9 LEDs, depending on the state of the other pins. I figure that I'll have to have 9 of whatever circuit I'll use to adapt the voltage from 5 to 2.
The LED I'm using is the Dialight 598-8610-207F, if that helps.
