This project shows how to connect an LCD screen to an Arduino Mega 2560 and use potentiometers (knobs) to adjust the screen’s contrast and control an extra function, like brightness. Explaining the ...

The most popular display system widely used in Arduino projects is the liquid crystal display (LCD). LCD displays consists primarily of two sheets of polarized glass plates with a thin layer of liquid ...

Your LCD display should have 16 pins coming out from the bottom. The LCD display needs 6 arduino pins, all set to be digital outputs. It also needs ground and 5v ...

The pH scale is used to measure the acidity and basicity of a liquid. It can have readings ranging from 0-14, where 0 shows the most acidic liquid and 14 shows the most basic liquid. 7 pH is for ...

One of the limitations of the small 8 bit microcontrollers like the Atmel ATMega family adopted by the Arduino board, is the reduced number of I/O ports. Among the main advantages of these ...

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially when we ...

This project demonstrates how you can build a real-time clock (RTC) with a temperature display using Arduino, DS3231 RTC chip, and SSD1306 OLED display (128×64 pixel). DS3231 RTC chip is more accurate ...

Often times, we need to secure a room at our home or office (perhaps a secret dexter’s laboratory) so that no one can access the room without our permission and ensure protection against theft or loss ...
