In today's lecture, we will design a project in Proteus, where we will Interface Gas Sensor with Arduino. I will provide the complete code and simulation. Gas sensors are widely used in fire alarms, ...

A library for driving LiquidCrystal displays (LCD) by using the I2C bus and an PCF8574 I2C adapter. There are modules that can be soldered or stacked to the display that offers an I2C interface for ...

This library allows an Arduino board to control liquid crystal displays (LCDs) based on the Hitachi HD44780 (or a compatible) chipset, which is found on most text-based LCDs. This library is free ...

This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual intervention. It is built around an Arduino Uno, which is programmed to ...

The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...

To build an FM receiver, developers can use highly integrated chips, such as the TEA5767 from NXP. Here we describe an FM receiver with a frequency range of 76 to 108 MHz and 2 x 3 W stereo sound ...

In this digital age, we come across LCDs all around us from simple calculators to smartphones, computers and television sets, etc. The LCDs use liquid crystals to produce images or texts and are ...
