Always under-watering or over-watering your plants? Wire up this Arduino-based sensor and save them.

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, ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very ...

So if you want to modify it to add more fans, change the message on the LCD, or use a different temperature sensor, you can easily give it a go even if you're a beginner at Arduino coding.

After the temperature sensors detect deviance from the set point, or upon SMS instruction, the Freeduino will crank up the heat through a 5V relay attached to the home’s boiler.
