Re: Is there an easy way to do PWM yet?

Tried it out last night, and of course you were right, with 5v the blue led showed up. Now I need to track down some MOSFETS.

Re: Powering the pyboard

All perfectly clear to me now, thanks!

Re: Header Sockets

I guess 2.54mm pitch sockets are what I need? It turns out the ones I ordered and broke all the hell last night were these: https://www.sparkfun.com/products/115 resold through a supplier in Japan http://www.switch-science.com/catalog/505/ Maybe I'll try by luck with these http://www.switch-science....

Re: Powering the pyboard

Gotcha, I think I had my wires crossed a little when I asked that question, but putting higher voltage in to vin won't result in higher voltages at the pins, it will just result in waste heat on this board, is that correct? On the arduino apparently if you supply higher voltage via the dc jack, you ...

Re: Header Sockets

Thanks again Dave! I am in Japan, and it has been more challenging that I would have thought to find electronic hobbyist type shops like adafruit and sparkfun, but I've managed to find a few. the machine pin sockets terminology may be useful, and the measurements definitely are because I don't truly...

Re: Is there an easy way to do PWM yet?

Dave, I really appreciate you taking the time to walk me through all of that! I guess my things to try once I get home are hooking the blue lead of that tri-color directly to 5v and see if it lights up, then see if I have MOSFETs among the components I have lying around and try that out. It mentione...

Header Sockets

Some header sockets came with my micropython board, but not enough to solder sockets on all of the pins. I would like to add in two more 8 pin socket rows. Does anyone know a good place to source the same header sockets that were included in the kickstarter packages?

Re: Is there an easy way to do PWM yet?

Also, if this is the LED used on the board I have, as it appears to be, it looks like the red is a lower voltage than the other two colors that are just a smidge below 3.3V

Re: Is there an easy way to do PWM yet?

Thanks Dave,

That is really helpful. I have one of these.

It looks like it has resistors inline, do I still need to add my own resistors to the circuit?

At any rate, I'll read up on the MOSFET. There are a lot of things I really need to learn before I'll be semi-competent at this.

Re: Is there an easy way to do PWM yet?

Brilliant, here that is powering an RGB led, though it turns out on the third setColor() because my blue led component seems to not be working. (I voltage tested, and there is more voltage getting through on that third pin than the others, so it seems not to be a problem of the board or the code. im...
