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 ...

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 ...

If you are thinking about building your next project around a 4-digit seven-segment display, you need at least 12 connecting pins to drive all the segments properly, that is most of the pins for a ...

Testing And Code Execution Referring back to the circuit schematic, I designated digital pins on the Arduino for Clock, Data, and Chip Select. The host board's connections and common pins ensured ...

Each connection to the Arduino I/O drives an LED anode, while the cathodes are joined between the diodes of each plane and go to lines A, B, C, and D, which will be cycled to logic low. So, as far as ...

Link to video: I'm using dual 7-segment LED displays in another project, but I figured I could have designed that using fewer GPIO pins than I did. So I tried out my theory here. Now, first things ...

For the RGB LED, each color pin is connected to a PWM digital pin on the Arduino. These pins output the corresponding color's value. Each of these pin's jumper wires passes through a 220 Ω resistor ...

Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.
