rayjorgensen‘s ultimate goal is driving a solenoid with Pwm. He started by requesting help in getting one to switch at all as this wasn’t working for him.The discussion has been around that. Or are you asking why one would want to drive a...

Like paul says, and I probably should have said.. get a diode on there. I looked up my notes on that project and I measured 450V from the 12VDC solenoid valve I was using when switched instantly using some wire!!. I'm not fully convinced I...

When I was looking for a logic level driven mosfet for low fuss I chose an IRL540N https://pdf1.alldatasheet.com/datasheet-pdf/view/88237/IRF/IRL540N.html. Ignore whatever the device name is in there as I have selected whatever I could find in...

perhaps the device really doesn’t work from 3.3V like it says it does. You could test that with some wires,3.3v and a multimeter. or perhaps your wiring on the teensy is wrong.. missing ground connection.. need to power off and double check with...

@AndyA Thanks, that clears a few things up for me regarding headers. I’m motivated to go back to a project and re-organise with classes and separate compilation units if for nothing else than to see how much i can speed up compilation and...

I don’t think I’ve really understood the function of headers. If I’m understanding what you’re saying I’m now wondering why I see #ifndef,#define,#endif stuff around arduino headers. The benefit of enforcing only one instance of the class is to...

Hello. I have a simple task I find myselft doing repeatedly in Arduino projects, timing sections of code to see how long they take to run. I've finally (after 5 years) got the hardware of an 8x8x8 ws2811 LED cube mounted safely where the cat...

I downloaded your simulator and i like it. It has given me some ideas. Thanks. Note to others like me who may not have known you will need to do a pip install pygame to run the simulator. (but it does say that in the instructions)
