Learning how to use an Oscilloscope

@inst-tech OOPS, I should have mentioned, this is a push to lock power on rig LED, it needs 12 to 24 VDC. I will use a MOSFET to give them 24VDC and control the MOSFET with either the 3.3VDC (lights but less bright) or add a level converter to change the 3.3VDC signal to a 5VDC.

Thanks for rating the point, that kick started my memory so that I recalled what I just explained. It also explains why I have an IRF520 module sitting on my desk.

I will try to make a diagram when I have it designed (80%) and bread/perf boarded to prove it all works. It's no big deal, I just took Bills Linear PSU and eliminated the switch to bring out 3.3VDC, 5VDC, 12VDC and 2-20VDC posts each with a meter and on/off switch. That way I can have 1 to 4 voltages at once. Hmm, I should really have a total AMPS in there as well but I think it's unlikely. If anything will pull power, it will be the 12 and I have another supply I can use for that if needed.

Thanks again.

At the moment I am trying to get my Pi4 to work with a Logitech Wireless Mouse/kbd combo but no luck yet.
