I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

Cooking is all about temperature control: too cold isn’t good enough, and too hot can ruin everything. To aid in this regard, ...

I borrowed most of the Arduino's programming code from Iseman's project and uploaded it to the Arduino (See Below). The LCD display showed moisture, temperature, and light readings in variable ...

There’s also an LCD display and a FET to control the heater. The idea behind a PID controller is that you measure the difference between the current temperature and the desired temperature known ...

The project is equipped with a DHT11 sensor to read the room's temperature and an LCD to display this temperature reading and the speed the motor is currently running at.

The Arduino compatible Pax Instruments T400 Temperature Datalogger is now available to purchase priced at $175 from Adafruit. If you liked this you might also be interested in building an Arduino ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...
