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.

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 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 ...

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 ...

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 ...

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 ...
