The GND of the 9V battery is not connected to the GND of the arduino. So, this cause the fan unable to move even if the temperature exceed the threshold temperature. Solution 1. Connect the GND of the ...

You also need to select the transistor by the type of fan that you use. In my case I used the well-known BD139 transistor and a 9V battery to provide power to the fan and transistor. The LM35 ...

A common hacker upgrade to an espresso machine is to improve stability and performance with a better temperature controller, but [Schematix]’s Smart Coffee project doesn’t stop there. I… ...

The open-source ProductivityOpen platform provides all the great features of a standard Arduino plus the added power and reliability of an industrial controller. The processor circuit of the P1AM-100 ...

A programmable temperature and process controller for use by the maker community has been designed to be Arduino-compatible. Called the SmartPID it can be programmed on a PC via the USB port using the ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home. Head over to ...

Tinkerers take note, because Arduino has launched its new Esplora controller, which just so happens to be customizable and open source.The Esplora is derived from the Arduino Leonardo, but unlike ...

Arduino Shields, like the Xbee wireless communicator, aren’t compatible with the Esplora out of the box, but any existing Arduino software should work with the new pre-assembled controller.
