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 ...

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 ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to … ...

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.

Recall the last time you tried to dim an LED using pulse width modulation. I am sure you have experienced the relationship between the duty cycle and the perceived brightness is not linear at all. The ...

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 ...

All the info you need right here ✦ In this occasion I'll make a lighting system to be controlled remotely from my rc using ...

Do this before you sew anything onto your sweater just to make sure the LED string will correctly fit the pattern you drew. Start with the end of the string so the Arduino ends up at the bottom of ...

Arduino_LED_Matrix API is available for programming and control, and “we have developed a graphic tool designed to help makers create and export their own animations”, according to Arduino.

As you can see from that sketch and the circuit diagram, the LED is connected to the digital pin 13 of the Arduino. Once you verify (compile) the sketch and upload it to the Arduino board, you should ...
