Review: Adafruit 16x2 OLED Display

I was surprised not to read anything about this behavior in the article.

Ah, you see I am a Mac person.

However, there is the annoyance on the Mac, that every time you plug it in, it decides you have got a new keyboard and invites you to identify it by pressing certain keys. Fortunately it carries on anyway, so you can just ignore the window.

@Si: But doesn't that mean that ALL ARM Cortex M3 and various other companies' 32-bit microcontrollers, have no applications?

Not amongst Hobbyists I expect.

Still waiting for the flood of examples

However the small SRAM space and limited clock speed on the 8 bit AVRs does rule out many valid hobbyist level projects that really can't be performed on the existing arduino hardware.

Maybe I am lacking imagination, but how about some examples?

My fear is that too many begineers will choose a Due over a Uno based on their possible future requirements rather then picking the best board for their entry into this hobby.

Definitely, a lot of people tend to buy the latest and best, even if it isn't the right one.

I just don't get the Due concept. I just feel I must be missing something obvious. Someone please explain it to me.

Surely, if I need more processor, then its because I'm doing something fundamentally unsuited to an operating system-less device like the Arduino. I.e., image processing, DSP, MP3 playing etc. If I need an OS I'd have Linux on a Raspberry Pi.

Arduino is a device for electronic hobbyists. 16 million things a second is faster than I've ever needed an Arduino to perform.

For what its worth, my experiences of using the Leonardo.

Come mai vuoi imparare l'italiano? Vieni a vivere in Italia?

Oggi anno ho visitato l'Italia (vacanza).

In 5 anni, quando tutti i bambini ha lasciato a casa, vogliamo vivere in Italia per alcuni anni.

Scrivo ovunque - occupazione mobile!

5 anni per imparare l'italianto senza Google Translate

dai un occhiata a questo free ebook sull'elettronica:

e questa è un free samples della rivista elettronica in:

Grazie.

@Madwriter

Cambio posto?

Si, certamente! 10C, pioggia, vento!

Vorrei estudiando Italiano da solo, pero capisco electronica perché scrivo libri su elettronica.

Ho 3 Elektor inglese. Chiunque cambio per 3 riviste en italiano?

Grazie mille,
Particolarmente per le correzioni.
Eccellente - più riviste in Italia che uk.

Sto studiare l'italiano. Ci sono riviste di elettronica in italiano che ho potuto leggere.
Sia on-line o su carta.
Raccomandazioni per favore.

Haven't you ever tried a j-turn in your car. Full speed reverse, full lock of the wheel and jam into drive. Totally normal! ;-)

Ha - no, not tried that.

But then thats fine because engine and momentum are in agreement by the time you lift your foot off the clutch.

Ah, sorry so solar charges battery, then battery charges other things. The battery bank expects 1A at 5V, if its charging a LiPo, then it probably does expect to have 1A available for its smart charging.

You could use a good old 12V lead acid battery charges from the solar and then a 7805 or higher power providing the 5V out to the camera etc.

A 7805  can cope with 35V input. Presumably you got 5V out with no load. If the camera expects to be able to draw 2A, (which seems a lot) then the solar panel isn't going to supply more than 200mA, so the output voltage will drop.

is it fundamentally bad to send a motor in full reverse from full forward

Ouch, Yes. I don't think you would do that to the gearbox of your car? Full speed forwards then slam it into reverse!

Stop it, then reverse it. The capacitor is not going to store a significant amount of energy in comparison to the kinetic energy of a 150W motor!
