Hi, sorry to ask a question like this but I'm an absolute novice.
I'm able to do the simple wiring but unsure how to connect it all together.
I have these laser units
And these switches
Obviously AA batteries and wire.
The main question is how best to wire this up. If possible two laser and one switch but if that's impossible then two separate circuits
Thanks in advance
Not too sure why you need laser pointers but anyway. Depending which PDM you may have some have a dedicated 5v output which might work. This only puts a small amps you'd have to check. The PWM will give a lower voltage than battery but its not stable. If its set to 50% it 50% for the power supply at that time. Which could be 11 volts upto 14 depending on load. yes you could use a maths channel to to try to stabilize it 50/(Bat voltage/12) but from what ive seen the pdm isnt quick enough to keep it stable. Attentively you can get a12v to 5v step down which i have done to use 0-5v sensor going to the pdm.
