1. Bitshifters don’t have 6 channels of PWM output and 8 channels of analog input. 2. Now that you offloaded I/O to the second core, you can start thinking about other more complex scenarios ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

As for the pins, the UNO features 14 digital pins for both input and output use, six analog pins for input only, three ground (GND) pins, a VIN pin for connecting to an external power supply, two ...

“Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing ...

And that involves setting pins to ‘interrupt-on-change’ and getting the chip to ‘wake-on-interrupt’ – all stuff I could have done in assembler, but how to do in Arduino-speak. Big Dan rides to the ...
