In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

Analog input A0 Used for the temperature sensor input, through which we will obtain the system temperature. Digital inputs (PWM) 3, 5 and 6 Used for the rgb led, through which, varying its values ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

Now that summer is coming, it’s time to break out the Air Conditioners! There are some old AC units out there that still work just fine, but nowadays we are used to everything being remotely ...

Never get between a man and his salami. [Mike] needed a way to control temperature, humidity and airflow with his meat curing setup. Of course he could modify a refrigerator and humidifier to be ...

Reads the analog temperature sensor every 100 ms. Converts analog value to temperature (°C). Stores it in a shared variable currentTemp protected by a mutex. alarmTask Checks the current temperature ...

How can you remotely control home heating? Here’s an SMS remote control system using the mobile network, featuring relay outputs and a temperature sensor. It’s based on an ATmega328P and the Arduino ...
