It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

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 ...

In this project, we will demonstrate Arduino AC fan speed control using TRIAC. Here phase controlling method of the AC signal is used to control the AC fan speed, using PWM signals generated by ...

This code is written to control a 12v 4-pin fan based on temperature readings from a dht22 sensor through pwm.This project used an arduino uno. The code assumes that the dht22 sensor's output pin is ...

Temperature Controlled Fan Using Arduino This project demonstrates the development of an energy-efficient system to regulate a fan's speed automatically based on room temperature. By integrating an ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.
