When coding Arduino projects for other people (and myself) I find having ASCII art pinouts of the hardware very helpful. It allows me to very quickly see the pin assignments and pins used. Please feel ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

The Arduino has long been a favorite among electronics enthusiasts of all levels of skill, and it’s easy to see why. Whether you’re a beginner or a seasoned pro, the Arduino makes it easy to create ...

What This PR Changes This swaps the pinouts of the Red and Green led. I believe the current example has them wrong (at least produces the wrong colours on my board). It also seems intuitive that the ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

Our LED cube project then needs the following elements: Arduino Nano board; 64 LEDs of the preferred color; Matrix board to hold the LED structure. On the Arduino, we’ll upload our custom sketch, ...
