In this article, we will learn to interface a compact and monochrome LCD display named Nokia 5110 with Arduino Nano. This article will also demonstrate how we can display alphanumeric characters, draw lines and other shapes and even display bitmap images after converting them into a data array via “Nokia 5110”. Introduction of Nokia 5110 LCD Display: Nokia 5110 is a low-powered, inexpensive, and easy-to-use LCD display module. This display features a low-powered CMOS LCD controller/driver called PCD8544. The PCD8544 is designed to drive a graphic array of 84×48 pixels…

In this article, you will see how to interface GP2Y1010AU0F Dust Sensor with Arduino. GP2Y1010AU0F is an optical dust sensor that can detect very fine particles such as smoke, environmental dust, etc. It is designed for application in commercial air purifiers. However, it is also used in air conditioners and portable air quality monitoring systems. This sensor can detect dust particles up to the size of 0.5 µm. Features of Dust Sensor GP2Y1010AU0F Can easily differentiate smoke and house dust Consumes less current: 20mA max Sense dust particles in less…

The majority of Microcontroller Units (MCU) include a limited amount of storage space that is adequate to hold your code or software. The Arduino Mega (ATmega2560) has 8 KB of bootloader space, 256 KB of flash memory for code storage, 8 KB of SRAM, and 4 KB of EEPROM (which can be read and written with the EEPROM library). The issue now is what to do if you need to store data for applications like data loggers, data visualization, etc., but the microcontroller unit memory is too small to be…

In this article, we make an Arduino Countdown Timer using P10 Display. The counting is done by Arduino and then displayed in the P10 LED module. This project might come in handy for time-keeping purposes during physical games. The details about pin configuration, display specifications, and hardware interfacing between Arduino Nano and P10 are referenced from the “Interfacing P10 single color LED Display with Arduino Nano” article. In this article you will learn two things: How to display a countdown of 3 minutes in P10. How to include a Reset…

The P10 LED display is a single color (red, blue, and yellow), high brightness, lower power consumption, and long lifetime display module designed for semi-outdoor use. One display module we are using contains 16×32 = 512 LEDs. In the tutorial “Interfacing P10 LED Display with Arduino“, you will learn: How to interface P10 Led display with Arduino How to select text font and size of the character How to display static character and running character.   Introduction to P10 Display P10 display is a dot-matrix LED display. Dot-matrix Led means a…
