8x8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8x8 LED Matrix module ...

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 calculator uses a full 16 button matrix keypad. The Arduino deciphers button pushes with the help of the Keypad library, at which time the appropriate character is displayed on the 2×8 LCD ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

But having a 4×4 button matrix that would indicated a random button to press sounded tougher to get around, so the idea for this project was born. It also looks suspiciously like a midi ...

Arduino enthusiasts or those looking to learn more about programming with Arduino and electronics-in-general may be interested in a new Kickstarter campaign and Arduino compatible 42-Digit SPI ...

While you hopefully don't need one-button access to 911, a desk-mounted panic button is undoubtedly cool, and it makes for a great DIY Arduino project. You'll need a prepaid SIM card, an Arduino ...

The OONTZ uses a 3D printed case, a 16 button keypad, an Arduino Leonardo, a monochrome driver, and a few potentiometers. It's actually a pretty simple thing to build yourself provided you can the ...
