The exception is the Arduino Nano’s A6 and A7 pins, which can only be used as analog inputs.pinMode(A0, OUTPUT); digitalWrite(A0, HIGH);Some pins also have additional functions which you can find in the table below:Pin numberPin nameTypeSpecial function 1 D1/TX Digital Pin Serial ...

The modifications are pretty simple, all you need to change is the I/O pin numbers used for the pushbuttons, as the ones in the original sketch are not all available on the Arduino Nano ESP32 board. Here are the corrected pin numbers: Modification to Mouse Sketch 1 2 3 4 5 6 /...

The Icarus is a cost-effective cellular IoT board built around Nordic Semi's nRF9160 modem and combines LTE-M, NB-IoT, GPS, accelerometer, USB, LiPo charger, as well as an eSIM with free data out of the box and a nano SIM connector. Control, monitor, and keep track of any asset, ...
I welcome you to the second part of tutorial. In this tutorial I show two things. In first part, I shown how to develop application for nRF52840 MCU presented on Arduino Nano 33 BLE Sense without Arduino IDE. In this second part I...
Why is needed the resistances, because if se a ardiono not nano is not necessary. Thanks a lot Reply Martyn If you mean the voltage divider it is because the Bluetooth RX pin is 3.3v and the Arduino Nano is 5V. Many people do connect the Arduino directly to the BT module and report ...
