Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

This project combines two Arduino Uno boards: one as a master and the other as a slave. The master Arduino handles the LCD display and temperature monitoring using a DHT22 sensor. The slave Arduino ...

Seven-segment displays and monochrome LCDs are fine for most projects, but some things simply look better in color. [John] over at the Little Bird Electronics blog recently wrote up a tutorial ...

This project implements a password entry system using Arduino, where users enter a 4-digit password via a keypad, and the entered password is displayed on an LCD. If the password matches the preset ...

The Arduino is a cheap electronics board that allows you to make your own electronics without a ton of coding experience. We love the Arduino, but like any electronics project, coming up with ideas ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...

ChatGPT, a language model trained by OpenAI, can be used to generate projects for Arduino. Arduino is an open-source development platform that allows users to create interactive projects with sensors, ...

So you've already outgrown Arduino's most beginner-friendly board, the Uno, and are looking to move on to bigger, more exciting projects. In that case, the Nano family might just be what you need.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this ...
