Hi Zedz,
Welcome to the forum!!
Just to confirm were you looking to power the Arduino with the ‘Wireless Charging Module’?
If you connect it to the 5V pin it should work.
In regards to question 2: were you looking to control the LEDs via this module through an IO pin?
The IO on most Arduino’s can only output milliamps of current, this module requires can drive up to 1A and expects a DC input - so no PWM (so that the onboard circuitry can control the pulsing to ‘transmit’ the power - this module is a transformer, it just comes in a different form factor).
Question 3: You can definitely reduce the voltage although you’ll need another module to do so, since this is a switch mode device I’d steer well clear of cascading another.
If you’re trying to get some LED’s in tight places, I’d check out Chris’s project here: Hogwarts Lights - Tutorial Australia
