Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...

Taiwan's LCD panel industry, which peaked at over NT$1 trillion in 2007, collapsed within years and became unprofitable. The decline pushed many optical materials suppliers to diversify. Alliance ...

AM232X is a sensor similar to the DHT12 with an I2C interface. Although in theory this could enable multiple sensors on one bus the AM232X has a fixed address 0x5C so one need to implement a ...

Learn how to easily adjust the contrast of a 1602 LCD display using Arduino. In this quick tutorial, I’ll show you a simple trick to control the contrast electronically, without relying solely on the ...

In chemistry, solvents (generally in liquid form) are used to dissolve, suspend or extract other materials, typically without chemically altering either the solvent or the other materials. Solvents ...

This project is designed to implement a smart home system using the ATmega32 microcontroller, sensors (LM35, LDR, Flame sensor), an LCD display, and a PWM-controlled motor. The system automates ...
