Hi
I recently purchased a 300-3000mA Buck Regulator LED Driver for 1-100W High Power LED from
Sure Electronics
The driver supports an input voltage of 10-45v DC and supports PWM dimming.
But I am not sure how to connect the PWM to an Arduino.
The basic layout of the board is below
The VCC is connected to an external voltage source of 10-45V and GND connected to that same voltage source.
The EN pin is described as PWM terminal.
When applied with ground or suspended, full amount of current will be output and when connected with +5v or VIN, output current will be 0.
My question is how would I drive this from my 5v arduino without destroying my arduino?
