Make an EC/pH/ORP/temperature sensor device to monitor water. Interact with it through a website using Bluetooth Low Energy.

2 wire 8 channel Relay Module || Reduce your CPU workload by interface 74LS164N.

An Arduino Nano used as an IO expander on I2C for ESP8266. For example, add 8 digitals IO and 6 analog inputs.

Hacked MP3 player remote as DC motor driver.

This project implements an Arduino Library that leverages Mbed OS and makes getting started with the Nano 33 BLE Sense simple!

I've invited fellow writers and now one book is missing. Time to make a lie detector with Arduino Nano.
