Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

The Power Supply schematic includes a 5vdc Sensor regulator. This reduces the load (and heat generated) on the Arduino on-board linear regulator, and also allows more effective input protection by ...

The Arduino takes this input, converts it into degrees Celsius, and compares it to a predefined threshold value, such as 40 degrees Celsius. In the first scenario, if the temperature reading from the ...

Arduino UNO - The Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB ...

Circuit Diagram and Description As shown in the schematic diagram above, it contains Arduino board, LPG GAS Sensor Module, buzzer and 16x2 LCD module. Arduino controls the whole process of this system ...
