This 4 -digit 7-segment display section is wired around four common-cathode 7-segment LED displays, and four BC547 npn transistors. The 1K resistors are used for base current limiting, and the 390R ...

This repository contains a collection of five exciting projects for the Arduino Uno R4 WiFi board. Each project demonstrates creative use of the Arduino_LED_Matrix library and explores unique patterns ...

One more suggestion: if we use an Arduino PWM pin as the common anode pin, we can power on/off the display and change its brightness. What if using Common Cathode Display. If we put in the sockets ...

The board has four LED arrays resulting in a display of 8×32 LEDs. The MAX7219 takes a 16-bit data word over a 10 MHz serial bus, so programming is pretty easy.

The display shield and board are housed in the ProtoStaxAG Enclosure for Arduino Giga Display. This demo helps you get started with the Arduino Giga Display Shield and also showcases how you can ...

Another day, another Arduino project. This time it's something called SuperDuino, a tiny touchscreen powered by a coin cell battery and backed up by a tiny Arduino-Like processor. The kit can be ...

An Arduino can handle running a small LED cube on its own, but if you’re planning on building something big, eventually you are going to run out of pins. For something like an 8x8x8 cube, odds ...

Be still my beating heart! Andrew O'Malley's pulsing heart lamp looks alive with two Arduino-controlled settings: soft beating and cardiographic wave.

The Adafruit Metro RP2350 is a Raspberry Pi RP2350 development board that closely follows the Arduino UNO form factor for compatibility with existing Arduino shields.. Key features include 37 GPIOs, a ...
