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 ...

The PWM output pins on the two boards also differ, with the Nano having six (D3, D5, D6, D9 to D11) and the Micro having seven (D3, D5, D6, D9 to D11, and D13). You'll notice a difference between ...

If your Arduino runs out of I/O lines, you can always add one of the several I/O expander chips that takes a serial interface to set its several pins. Or perhaps you could buy something like an Ard… ...

It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than others. For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino ...
