Nixie thermometer – let’s display the temperature

Today I wrote a sketch that merges the previous ones: reads the temperature from a thermistor (connected to PIN A0) and displays it driving two nixie tubes. I also added a third nixie, to display symbol °C. This tube is not controlled by Arduino but it’s directly connected to the power supply (and therefore it’s always on): The sketch is…

irrighino

Irrighino is a complete watering system, based on Arduino Yun. The main features are: [checklist] a configurable number of solenoid valves an AJAX web interface a weekly schedule manual activation / deactivation [/checklist] Here’s a short video that describes the project: How it works An Arduino Yun – the “brain” of irrighino – is connected to the switch panel…

MobileRelays – enc28J60 and Arduino (21)

Today’s project, as always based on the enc28j60 ethernet controller, allows to toggle relays (or, generally, digital PINs) using a responsive web page, that is a page that automatically adapts its layout to devices with different screen sizes (for example your smartphone and your PC). Video presentation Web site The web site, stored on an SD card and…
