Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or ...

Once he received the boards, alll of his prototyping components were swapped out with SMD versions, including a TQFP ATMega168 chip in place of the full-sized Arduino board.

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

This has led to a proliferation of Arduinos manufactured by different companies, each bringing their unique touch to the platform. Arduino boards a complete guide ...

Case in point, Instructables user botdemy’s message board that displays a message sent from a server. The Pi hosts a web server that translates any block of text into a scrolling LED message.
