Frequently Asked Questions
What should I watch out for on the Arduino Nano?
A6 and A7 are analog input ONLY — no digitalRead/digitalWrite. Clone boards often need the CH340 USB driver and the "Old Bootloader" option.
Is the Arduino Nano 5 V tolerant?
5 V logic. Many modern sensors are 3.3 V, so check before connecting them.
