Arduino Rack Temperature Controller. ... Initial design was based on a separate (non-shield) board using a MAX31790 for fan PWM control and tach measurement integrated with an Arduino Uno using I 2 C.

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 ...

The Arduino board’s microcontroller (MCU) ATMega8/168/328 allows for rapid, dynamic control, and the LCD screen gives real-time temperature and fan speed data for convenient monitoring. This project ...

This isn’t just a simple controller, either. It is a modular design with an Arduino Mega and a lot of I/O for a serious fish tank. There are controls for heaters, fans, lights, wave makers and ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting real-time data on soil moisture, temperature, and sunlight. From sensor ...

For one, the sound doesn’t directly control the solid state relay used in the fan controller. When the microphone equipped Arduino detects enough noise, it will start a timer that keeps the fan ...

I had to use a little Java program to determine the three coefficients not wanting to use a long lookup table. I added a PC Fan to control temperature overshoots. 3 - Logging. Temperatures and PID ...

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 user sets ...
