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 ...

You can get a long way just using the matrix library, but there is another library, ArduinoGraphics, that has additional functions that make the LED matrix really useful. However, at the time of ...

In the previous chapter, we used a light sensor to read the ambient brightness as a value from 0 to 1023.This time, we will ...

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 ...

The Arduino UNO-Q is a new board from Arduino, combining an MCU and CPU sharing calls and data. I developed an UNO-Q based ...

The 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...
