For those people unfamiliar with Pins.h, presumable those people who haven’t purchased Far Inside The Arduino or Far Inside The Arduino: Nano Every Supplement, this file describes a structure over the GPIO pin interface that is much more efficient than using pinMode, digitalRead, and digitalWrite. For instance, we can execute ddr.digital_2 = 1 to change …
This post was intended to compare the different general purpose Arduino boards. However I’ve been slowed down by the week of fires and hazardous air here in Oregon. I haven’t completed my investigation of the ATmega32U4 yet, and, in fact, my sample Arduino Micro, which uses this microcontroller, was delayed over a week in arrival. …
Basically, “General Purpose” means those consisting of little more than the microcontroller, USB interface, and voltage regulator. In my last post I mentioned the Uno as the base-line board, with the historical lineage from the original Arduino board. But today you can get many different boards differing in size and microcontroller. In my next book …
In looking at the different general purpose Arduino boards available today, I’ve been thinking of how to tie them all together. So I’ve delved as well as I can into the history of Arduino boards. Frankly, it isn’t particularly easy to do. But I did find what appears to be the starting point — the …
