Overview In this tutorial, we will learn how to make led scrolling and animation display by using the 40*8 led matrix display module and Arduino. Most technologies use the dot matrix to display information such as cell phones, televisions, printers etc. It is commonly used to display time, temperature, notice,...

Overview In this Arduino tutorial, we will how to multiplexing seven segment display with a 74hc595 shift register. A single digit display shows 0 to 9 decimal number. Ofen we need to display two, three, four or more digit decimal number, but the problem is lack of I/O (input/output) pins in the MCUs. To solve this problem...

Overview In this Arduino tutorial, we will learn how to interface common anode and cathode 7 segment display with Arduino. 7 segment display is most common and popular display to show the number in the digital electronics and embedded system. It can be displayed in 0 to 9 decimal number.  They are easy to use...

Overview In this tutorial, we will learn how to interfacing 4*4 keypad with Arduino by a single analog pin. The use of a lot of pins can be reduced by following this procedure. It helps to use rest of pins for another purpose. For this tutorial, we will use a single analog pin to interfacing keypad with Arduino.  You...

Overview In this Arduino tutorial, we will learn how to make an audio player using Arduino and SD card module. Any kind of micro-controller project will look cool and interesting when we adding sounds. We can easily interfacing SD card module and Arduino. Also, we have easily found some Arduino libraries.  ...
